With the untouched version is creating the table by itself, with the edited version it's giving errors and i've created the table in database manualy.Something must be wrong in the code, even if i added the column to table in plugin and database smtgh must be wrong.

Did some modifications, added a var in the function and now is creating an empty table with the columns but not nickname.
