Why aren't Opencart 3 modifiers applied?

Question

opencart

Good afternoon!

I downloaded two modules: Clearing the cache and SEO Pro from opencart3x.ru. I installed it normally through the installer, successfully, they are in the list of modifiers - they are enabled, they are also in the modules - they are enabled. I cleared all possible caches, updated modifiers, changed the browser, reloaded ctrl + f5 and still the CNC Type item does not appear, just as the Cache Clear block does not appear in the admin panel. Although no errors were found in the ocmod logs and the modified settings file is on the hosting. What else can be done to enable CNC Type - SEO Pro?

Opencart 3.0.3.6
