The easiest way to upgrade is to upload a full copy of RUNCMS to your website while overwriting all files "except" mainfile.php and the running this upgrade script ..however it's more suggested to install a clean copy. In either case, before proceeding, it's strongly suggested to make a backup of both your site & database (see: phpmyadmin) in case something goes wrong! This upgrader only upgrade a single table this time Once done with the above steps, you should be ready to run this upgrader. When the upgrade process is done, simply change your file permissions as usual (all /cache folders to 0777 & all files in them to 0666), and then move any images (etc) you may have uploaded to the new corresponding folders. On the next page ALL MySQL errors will be listed ..but don't panik, errors with the following numbers can safely be ignored in most cases: 1046, 1054,1060, 1091 They simply mean your tables are either up to date, don't exist (for example a module that's not installed), etc.
