Upgrade System The following errors occurred while verifying that your server can run XenForo: All directories under /home/.../public_html/forum/data must be writable. Please change the permissions on these directories to be world writable (chmod 0777). Problem is that it's a directory added by an add-on and it's not allowing me to edit it's permissions or delete it. That and I don't have root access for the moment. Possible to suppress this check in the install process given that the rest of the directories are set correctly?
