Hello,
Recently there was a downtime at my host and they were doing some updates, once it was over I started experiencing a 403 error (access forbidden), after that I tried setting all files permissions to 777 (then reverted) yet no use, however this is not a issue I experience on all pages, its on certain pages such as editing account settings, reputing, editing themes etc.
Is there any fix?
Ask your host to turn off mod security.
