How to fix a bug in the opencart module?

Question

PHP

Good afternoon.
I'm trying to install a payment module for opencart.
After installing and trying to access the module management page, I get an error:
Fatal error: Class 'Controllerextensionpaymentsquare' not found in /vqmod/vqcache/vq2-system_storage_modification_system_engine_action.php on line 43
Any help would be greatly appreciated. Google hasn't returned any results yet.

Answer 1

for example, add the line to vq2-system_storage_modification_system_engine_action.php
of course, this must be done before calling the class Controllerextensionpaymentsquare
