i have tried to make the upgrade from Ver. 4.2.2 to the new Beta like you said but i will get everytime an error:
Fatal error: Database error in "/home/www/htdocs/xxxxxxxx.de/topsites/install/upgrade.php" on line 140
Table 'ats_settings' already exists in /home/www/htdocs/xxxxxxxx.de/topsites/sources/sql/mysql.php on line 79
And now nothing will work anymore!
What do i have to do that the upgrade will work without mistakes.
