In the upgrade instructions, http://www.revive-adserver.com/support/upgrading/ , in step 5 we set those folders to world writable, at the conclusion of the instructions we are instructed to change our var/site.conf file to 644 but we don't have any instructions on what our permissions should be for the 4 folders we changed in step 5. Just asking for clarification, I don't like leaving web folders 777 generally. Thanks
