OpenCart: "Modifiers" does not open after migration to another server— a fix is needed

Web Programming — incorrectly specified categories?

After transferring the site to a new server (OpenCart 3.0.2.0), the tab “Extensions → Modifications” in the admin panel does not work — when opened, it loads and the page hangs. No errors occur. The PHP settings and module set are the same on both servers. Everything else works as usual.

It is necessary to find the cause and restore the functionality of this tab so that modifications can be updated.

Response from technical support: Thank you for your patience. Unfortunately, we could not determine the reasons why the section you mentioned does not open. According to the strace utility and the xdebug module, the code execution reaches the file /admin/controller/marketplace/modification.php. No errors occur. The PHP settings and module set are the same on both servers.

Update #1 from 29 September 2025

After changing PHP to 7.4, the modifiers tab opens, but on the front end, spaces are cut off, which leads to the merging of some classes.

Hello.
I have extensive experience in troubleshooting and optimizing OpenCart installations, including resolving issues after server migration. The problem with the "Extensions → Modifications" tab freezing without errors is often related to caching, database mismatches, or minor differences in server configuration, even if the PHP settings seem identical. I will thoroughly analyze the change controller, database records, and caching levels to determine the exact cause and fully restore functionality. My goal is to provide a clean solution that ensures the seamless operation of your admin panel and its stability for future updates.
