I am having an issue with my WHMCS configuration where there are pages that redirect to the wrong place or to themselves. I have gone to General Settings and attempted to use all three options of Friendly URL Rewrite, Friendly Index PHP, and Basic Url and none are correcting the issue. I have disabled my redirection plugin and still have the issue. After contacting my host, they advised that the issue lies in the WHMCS Htaccess file, because when disabled, the problem is corrected, however it cannot be permanently disabled due to it writing the permalinks. So I think I am in a catch 22 at this point.
