Just upgrading my site from 1.3.2 to 1.3.3 and I have this error. The following errors occurred while verifying that your server can run XenForo: All directories under /var/www/vhosts/gtarena.com/httpdocs/community/data must be writable. Please change the permissions on these directories to be world writable (chmod 0777). Please correct these errors and try again. I do not re call having folders var/www/vhosts/gtarena As far as I am aware no file permissions have changed. The update from 1.3.1 to 2 was without issue. The only thing I did differently this time was use my desktop for the upgrade (first time) and copied the upgrade files directly from the desktop (folder) and dragged them into filezilla, rather than from transferring the files from within filezilla.
