Fine, thanks to stangger!

...and gnrx: don't touch the database again and mess it up :D ;)

That I thought at the beginning, that the problem was that "touch" the database, but no ... that was not the problem.
Coincidentally coincided with server migration, and this mod is the only one I have installed (as well as vb) which is, in the configuration of mysql on the server, incompatible with sql_mode = only_full_group_by
So I had to make the appropriate modifications to the mysql configuration for this mod to work.
That's right, until I found out that the problem was that ... I thought it was what I "had touched", xD
