I can't upgrade from RC2 to RC3… XenForo RC2 is installed on my local server.
I created a new folder, moved all files from the upgrade package to that folder and copied 'data', 'internal_data' and 'config.php' from the RC2 folder to the new location.
When I open the installation (new folder) I get the message that the forums are currently updated. When I open the installer I get 'Your server meets all of XenForo requirements and you're now ready to begin installation.'
It worked when I upgraded from RC1 to RC2 - what am I doing wrong here?
The first error message I get is 'You have already completed installation. If you wish to reinstall, please delete the file internal_data/install-lock.php.' - Removing that files gives me the message from above.
Strange, I got it working by typing in the path to the upgrade process by hand.
Problem solved, thanks.
