Upgrade PHP 7.4 to 8.0.3 issues

General Installation & Upgrade
1

Hello,

I recently upgraded my website to CS-Cart version 4.17 and decided to update the PHP version from 7 to 8. However, after this update, I encountered numerous bugs in the core files, and now I’m unable to access both the website and the admin panel.

Aside from upgrading to the latest CS-Cart version, are there any additional requirements or steps I should be aware of to make CS-Cart compatible with PHP 8?

Thank you for your assistance.

2

It should be compatible. I would guess that extension(s) were not installed when upgrading to PHP 8.0.?

Post the errors and someone may be able to help.

3

May be these errors are form 3rd party modules not compatible with php 8 ?

At first contact EnergoThemes (responsible for the et_content.pre.tpl file) and developer of the advanced_addon module

I also upgraded to PHP 8 from PHP 7.4 and I’m encountering the same issues in my Nginx log and PHP slow log. I get the same issues (RenderManager.php). Its made CPU utilization very high and made the website slow. I use Multivendor 4.16.2 Unitheme 2.
If you find out the cause, please share it.

advanced_addon comes with cs-cart

I’m still working on resolving the issue, and here’s what I’ve discovered so far: The website homepage loads correctly when accessed in English, but when attempting to access it in Portuguese (which is the default language), it triggers the template bug.
