Re: Error "Could not load file localisation/*.json" on checkout page
OpenCart 4.1.0.4 hasn't even been tagged or released, it is still subject to development and bugfixes. For a stable live shop we suggest using OpenCart 3.0.4.1 and PHP 8.3.

Re: OpenCart 3.0.x.x PHP versions support
The 3.0.x.x branch has now been updated, with added PHP 8.4 support, and a newer version of the cardinity payment method. Older PHP versions, like 7.x and 8.0, aren't supported anymore, one of PHP 8.1, 8.2, 8.3, or 8.4 is now required. We also changed the OpenCart version number to 3.0.5.0, to be us...

Re: UPS no longer working
Coming back to the subject of the UPS shipping extension: Is anyone using the free UPS Shipping and UPS Access Point™ : Official Extension ? Is it worth it to become a replacement for OpenCart's builtin old UPS shipping extension? I didn't think that one supports OAuth requirements, so it will no l...

Re: Upgrade 3.x to 4.x
Note : with OpenCart 3.0.4.1 sometimes minor "warnings" could happen (for example when a template .twig has troubles the twig engine will say some "deprecated .. etc. "). The developers are behind this "issue" and I guess they will release in a few days something calle...

Re: How can I speed up my OpenCart site? It's very slow on shared hosting.
It would be helpful if you could provide some more details about your OpenCart site, including extensions used, website URL, PHP version, webhost used etc.

Re: mini cart in header not updating to show option price
As paulfeakins suggested, set the product price to the lowest value option price, and the other option prices will show the higher price differences only. The mini cart always shows the calculated price correctly anyway. And there are extensions (such as our Instant Option Price Calculator ) which i...

Re: OpenCart 3.0.4.0 - PHP Notice: Undefined index: in catalog/controller/account/register.php
Looks like the account/register page is hit by spambots, in which case our SpamBot Buster should prove an effective solution for this.

Re: OpenCart 3.0.x.x PHP versions support
I was running composer on PHP 8.4. I'll try again with PHP 8.1. I ran the composer again with PHP 8.1, using below composer.json, and the resulting vendor libs seem to be fine now for PHP 8.1, 8.2, 8.3, and 8.4. The only issues were caused by some of the required packages for the "cardinity/ca...

Re: OpenCart 3.0.x.x PHP versions support
What version of PHP are you running composer on? You need to use the lowest version of PHP when updating. Using PHP 8.1 pulls v6.4.13 of symfony/filesystem. Or maybe able to use "platform" to set PHP 8.1 as the base. https://getcomposer.org/doc/06-config.md#platform I was running composer...

Re: OpenCart 3.0.x.x PHP versions support
@AddCreative: I think if I don't hear back from the author of the Cardinity payment extension, I might remove it altogether from the OC core. I just tested the "scssphp/scssphp": "^1.13" and it gets loads of deprecation messages when running under PHP 8.4. Hence we'll have to use...

Re: OpenCart 3.0.x.x PHP versions support
divido/divido-php should be removed as the payment extension was removed in 3.0.4.0. Yes, you are right. I also noticed when using the latest twig/twig package, one of packages used by it, namely the symfony/filesystem , requires PHP 8.2 or later, and won't work with PHP 8.1 or earlier, whereas twi...

Re: OpenCart 3.0.x.x PHP versions support
OK, it seems the majority sees it as an important enough change to justify the next version to be 3.0.5.0. I have tested some upgraded composer.json settings with later versions for the required packages, and so far this one seems to be the best one: { "name": "opencart/opencart"...
