As the title states, I am unable to push changes to any of the back end settings (mod manager, user accounts, scripts, etc) from any of the browsers on my PC. I don't even know where to begin with the diagnostics on this. It is worth noting that it works on mobile devices, but I am at a complete loss as to why none of the browsers on my Windows 10 machine load the site properly. I've used Firefox, Chrome, Brave, and even Edge and it seemed to work at first on the first two then Edge (Brave didn't work at all) but then it would just stop loading things properly like the add new user page or the mod manager scripts and applying changes would cause an application failure.
Disregard. Turned out to be a permissions issue with my account. Had it remade and the issues have been resolved. Can't confirm but it may have also been because of 2FA.
