Hello All

I have a problem during upgrade SMF from version 2.0.5 to 2.0.6. There is a "Unknown Error" in step number 4 "Database Changes" in moment "Executing: Changing column names".

Could you pleas give me any direction what can be wrong? Thank you in advance.

There are no database changes between 2.0.5 to 2.0.6 you shouldn't even be running the upgrade script..
