How to remove the error in Opencart "The requested page was not found"?

Question

opencart

Hello. For 3 days I have been thinking about how to fix the error "The requested page was not found!". The error creeps out when you click on the "View all" button (this link contains the address to the module to view all products).
Urls (URL) are in the SEO manager, everything is spelled out correctly, .htaccess without txt, updated the file cache, so far nothing helps, the error remains.
The problem is with several modules, the module with "Promotions" works fine, I checked it with other modules - there are no differences.
Categories and products and other pages also work without problems.

In the SEO - module address manager (add-ons):
module/latest - SEO Keyword - latests
module/featured - SEO Keyword - featureds

To everyone who responds and helps a huge huge like, gratitude, whatever you want, just help fix and remove the error :))
Thank you very much in advance :)
