I have been extending my site [login to view URL] both frontend and backend connecting its database remotely.
I have been looking into how rewrite rules work because my template is build on top of a lot of them for some tables, and I am so confuse about how they work.
I managed to link a rewrite rule-query_var-redirect template hook and make it work, but I am experimenting some issues beyond my patience.(all function calls are undefined from specific template).
I need 1 to 2 hours of help and formation on how do they work to keep extending my project and fix that actual issue.
