[core]: Upgrader Error
[ALTER TABLE `ost_filter` ADD `topic_id` int(11) unsigned NOT NULL default '0' AFTER `form_id`] Duplicate column name 'topic_id'
My suggestion would be to add a
WHERE NOT EXISTS or something like that to the SQL query so an existing table or a half finished upgrade doesn't kill the whole installation.
Maybe you could also catch the error and log it but still continue. If the end result is really not working, you could implement other checks to see if the newly added tables behave correctly.
Also, an auto backup would be much appreciated.
