Fix GROUP BY in dbstructure

[Alkarex]

#3440

[Alkarex]

The updated DB number might not be necessary, but it was to re-trigger the update process after the fix.
Since my instance was crashed in the middle of the update process, I had to manually do:

update configuration set v = 0 where k = 'maintenance';

I think this part should only be done when $ignore was false and $unique was true, since only then the following problematic queries are executed.

The updated number isn't necessary. (I had overseen that, could you change that back?) You simply could run php include/dbstructure.php update in the command line to retry the database changes. This would also reset the maintenance settings.

BTW: To reset the maintenance you can call php util/maintenance.php 0.

Here you are. And thanks for the info.

You might want to reset the database version in the config table to that the next database updates will be performed.
