Opencart, what about pagination when searching for tags?

Question

CMS

On the opencart site, if you go to the search tag ( click ), then we will be redirected to a page with products that has this tag, but if we go to any other page in pagination, it will redirect to the main page. There is an SEO PRO module, everywhere with pagination everything is in order, even if you search on the search page by words, not tags, then everything is in order with pagination.
controller code:
(click)

Answer 1

As times seo pro most likely and is to blame.
