IMPORTANT: It seems some users are having common problems when trying to upgrade to v6.01.2 from version 6.00.1xx, 6.00.2xx or 6.00.3xx. This is not a fault on our behalf, it's just a general misunderstanding by the user. PHPFusion 6.01 is a major update compared to its predecessors, therefore you need to follow the instructions to a tee.
1. First you must upload the correct upgrade script from the folder named 'upgrade v6.00.xxx' to the administration folder of your site.
2. Login to your site as the Super Administrator. Under the System Admin tab of the Admin Panel, click on Upgrade then click the button marked Upgrade. MAKE SURE the page reloads stating 'Database upgrade complete', failure to do so may cause problems later on.
3. VERY IMPORTANT: Since this release contains a number of structural changes, some elements of your site will not work properly until you have updated all of your files. YOU MUST upload ALL of the files from the php-files folder. Failing to upload all of the files will cause: no admin access, lower-center and right side panels mixed up, new gallery not working and more.
4. You should ONLY use the Photo Converter Infusion AFTER completing the above steps. It is designed to run under specific conditions which are created by the upgrade script and therefore will not work prior to upgrading. Be sure to verify the new Photo Settings under System admin before running the Photo Converter.
I sincerely hope this helps to clear up any confusion regarding the upgrade process. If at all you are any doubt please feel free to ask someone for help, there are plenty of knowledgeable users here who can help you. Thanks for reading!
