Back to the Future - with the speediest Freeware OpenCart Software ever designed !


Upgrading an existing OpenCart can be quite an adventure, with uncertain Results, if one is not a Coder, able to always get rid of still existing Misses + Faults in latest OC Releases first. But one now has a valid Alternative, based on the latest and most perfect OC (Release-Candidate) Version Code from the official OpenCart Github Developer Site, some time ago: OpenCart Download


History in Short, from my distant + neutral Swiss Point of View:
The OpenCart v. Version was never given 'Final v.' Status officially. In plain fear of Competition, I assume, because the not yet so great OC v.2.0 Release existed for some Months already, when the OC v. Version was made public on the OpenCart Developer Site. But most everything on Add-On's for OC v.1.5.6.x. Versions existed already. So, just re-announcing a new 'final' OC v. Version would have harmed the new OC v.2.x Extension Market, because OC v. would have been favoured by large Parts of the OC Crowd for still some time to come ...

Still, OC v. was 'codewise' nothing New, it was just a 'fixed + finished' Upgrade from OpenCart v.! It's Changelog can be found here: OpenCart Changelog

An additional Upgrade has been applied, to make the Code work up to latest PHP v.7.4.19, as tested and shown here.


Since it's Debut, OpenCart v. is known, to be top-solid, top-secure, and fast, and not a single Topic yet exists on OC v. - related Problems, from someone, using this Version, as I recall, during my almost 7 Years of rather intense OC Forum Activity (~12'500 Postings). And for me, all this makes OC still to be the Number One Choice , if one not only looks for Version Numbers, but simply for a proven solid and also simple to handle final OC Version Onlineshop Class Release, still capable, to be used with the latest PHP v.7.4.19 Release!

Johnathan, a competent OpenCart Moderator, just recently confirmed my Statements regarding 'overall' OC v.1.5.6.x Version Security here:

How to upgrade without destroying my site?


Ernie's OpenCart LIGHT is fully built on (secured and php v.7.4.19 upgraded) OC v. 'System' Code. I also replaced the outdated non-responsive 1.5.6.x default Theme with the famous Merkent Bootstrap Theme, known to be one of the 'speediest' responsive OC Bootstrap Themes around.

So, if you have an existing and well working OC v.1.5.6.x based Shop Installation, but still no suitable responsive Theme, the 'genuine' Merkent Bootstrap Theme v.3.0.1 is freely available here as Github Download. The Package includes a 'dark' and a 'bright' Theme stylesheet.css File.


You're in Front of a real Bootstrap Theme now. Different 'Merkent Theme' based OpenCart Designs can be seen here: - OpenCart v. with Merkent Theme Dark Style - OpenCart v. with Merkent Theme Dark Style - OpenCart v. with Merkent Theme Bright Style


And the 'OpenCart V-PRO' powered Site, linked below, uses regular OC v.2.0.3.x type Themes.
This OC V-PRO Demo Site is equipped with a Range of free Bootstrap Theme Samples:

Ernie's OpenCart LIGHT contains Parts of famous MaxD's legendary OpenShop Admin Extensions. An impressive range of most useful free VqMod (v.2.6.x) Extensions as well as additional Modules are Part of the free Download. It also includes a bright and a dark colored stylesheet.css File, to change Theme Coloring from dark to bright, by activating the corresponding VqMod.

OC-Newcomers: If you just want to get a well-done working Top Brand Online Shop Software, and you don't want to have a hard time, just to find out, how to get it to work, OpenCart LIGHT is the perfect Startup-Solution, to keep you from sleepless Nights. It just works, as it comes, and about 150 useful free + tested Enhancements and Updates are already part of the free OpenCart LIGHT Tester Package!

And the OC-Forum and Extension Sections contain Bulkloads of free Wisdom about OC v.1.5.6.x, if one plans, to change existing things, or add something new, for what reason ever. Free Literature and Youtube Information exists in Masses, if one wants to get familiar fast!

All this, and much more, combined with my Intention, to make this great + free OpenCart Online Shop Software to be the most solid, simple, and wisely equipped free OpenCart Release so far, as my Donation to the worldwide Community, for what I received on new to me Knowledge and Code.


PLEASE NOTE, that NO free Support is included and/or part of this free Offer, and/or can be expected. If no free assistance to Users is available at the OC Forum and/or Facebook OC Sites, paid Support might be required, if one likes to change existing things, or to add some Extensions. The Merkent Bootstrap Theme is slightly different from default OC v.2.0.x Theme Style and Files related, and 'global' OC Forum Knowledge might not always work out, if Custom Coding is part of an NON-DEFAULT OpenCart Installation, regardless of the OC Version and/or Theme used.

This needs to be clearly understud, fully accepted, and agreed on!

The whole OC Concept is not a free Gift from heaven, and not used, to create Fun, but Income, for most everybody involved! Ernie's OpenCart LIGHT v. Package comes for free, for Developers and End-Users, and/but that's all, you can expect, for nothing in return!


All open-source OC Code included comes as tested and matched, and/but without further Warranty, Obligation and/or Responsibility, from either Side. Please NEVER overwrite and possibly kill a working Installation, but install and test a new OC Software Version in a separate Subdirectory first, or you might end up in Tears!


Lots of free Knowledge and Wisdom on OpenCart v.1.5.x Versions already exists on many Sites, like linked below:

OpenCart at
OpenCart-Tips-and-Tricks Blog OpenCart Beginner-Tutorials OpenCart v.1.5 OpenCart Step by Step

to enable most OpenCart v.1.5.x Users, to likely succeed without much foreign Assistance anyway!


At least, if one does not plan, to waste costly time, and eventually a lot of Cash, to keep an older working OC v.1.x Platform alive + well. OpenCart V-PRO v. is the perfect and ultimate OC v.1.x Upgrade-Solution, to satisfy all Shop Visitors visual and technical Requirements, regardless of their Device's Screen Resolutions, and this, for still some Years (+ more 'latest' OC Releases) to come!

But please be aware, that older OpenCart v.1.5.x and v.1.4.x Versions may require a (usually paid) Database-Upgrade, to further function with OC v.1.5.6.x based Code.

Ernie's OpenCart LIGHT Software has been tested up to latest PHP v.7.4.19. It contains no hidden/encrypted Code/Links to any 'outside' Sources. 20+ 'basic' 1.5.6.x Admin + Front Language Translations are available for free on request, in - arabic chinese czech dutch english estonian finnish french german greek hungarian russian slovenian spanish swedish turkish ukrainian vietnamese e.t.c. - Language.

But only the default ENGLISH Admin + Front Language matches this OpenCart LIGHT Version in Full. Still, other Languages are easy to edit and complete by One of the Two built-in free OpenShop Language Translation Editors. Lower OC-2.0.x Version Language Packs can also be made usable without much work!

Be Aware of the Fact, that every additional active language will enlarge the Database considerably, one should therefore avoid to even 'test-install' not to be used Languages in the first Place.


Additional free Language Translations are available outside of OC Extension Section:

That's it, Folks. It's now up to you, to make your Choice! Either, keep on upgrading every few months, to, at best, end up with the same Face as before, or rely on an already widely established Solution, until a 'proven better' Successor will be ready, to take over ....

One last Info, to present Facts, when it comes to all those never ending and foolish 'blah blah blah blah' downtalking attempts, like about suddenly existing lacking Security and/or shrinking Support for 'older' OpenCart Versions. It's most likely only from those Developers, always looking for another chance, to frequently sell 'newest' and 'latest' Wisdom for the latest of 'never-final' OpenCart Releases again.

But OpenCart is a steady ongoing Project, and it's the only way to survive as well, as most all Coders are aware of. Just the larger part of OC Users never yet seemed to realize that. But they all learn, and some the hard way, just like in real Life too.

And later OC Versions are already listed on Hacker-related Websites, and latest OC v.3.x Versions even have severe Problems with latest PHP v.7.4.x Versions. But OpenCart v. was first published in November 2014, and during all that Time, it never got listed in Hacking Reports anywhere, besides of beeing capable already, to use latest PHP v.7.4.19 ! And with a very few slight Fixes, it will be ready to use PHP v.8.x as well. So, who are the real Fools, talking crab ?!

Packet Storm Bulletin OpenCart

And it required just ONE new System file, the same as OC v.2+ Versions too, to make it work with up to latest PHP v.7.4.19, as tested and shown here!

So, where is the Problem, to better still use something, already proven to work, during such a long time, as long as nothing 'Jounger' seems to be able to at least equal it's Quality, Stability, Security, Simplicity, and it's Performance ... ?!

OpenCart LIGHT Installation Software can be downloaded for free.

The OpenCart LIGHT v. free Version is now downloadable on my Github OpenCart Archive Account.

The Download Package contains a wide range of most useful Modules and VqMod Extensions, and Developers are free to create their own Extensions on OC v. LIGHT Merkent Theme Parameters.

If you plan to use another Custom Bootstrap Theme, available for OpenCart v. Version Code, the OC LIGHT System Code should work as planned. But it might influence overall Site Performance, compared with the unique highspeed Merkent Theme Design.


I strongly advise you, NOT to replace an existing online OpenCart Software with OC v. LIGHT Code, but install OC LIGHT as separate Shop, and test it first, before possibly ruining an existing Installation!


Good Luck ! Ernie
