SEO Module (SEF) for OpenCart 2.3

The abbreviations #SEO and #SEF actually mean the same thing. SEO - search query optimization, and SEF (URL) - friendly links. My module creates such links differently than other similar modules, which allows reducing the number of requests to the database. The link looks like this: domain/(language - optional)/1-20-desktops/1-27-mac (prefix - optional). In our example, 1-20-desktops means a category with id 20, that is, when following the link, the category is selected without querying the aliases table. If a language variable is specified, content for the specified language will be selected from the database. Detailed information on loading and setup is contained in the readme_sef file.
