I am running 1.9.4.1 and when I try to modify and submit a Global Content Block I get the "Forbidden....." message above.
The error log on my cPanel states:
I also get this when editing some other settings in the modules such as TinyMCE.File does not exist: /home/my-website/public_html/403.shtml, referer: http://www.my-website.ie/admin/edithtml ... lblob_id=1
I am sure it is to do with file permissions, but I cannot figure which ones need changing.
