mi dice:


Upgrading your databases:
Running 'update mt_author set author_type = 1 where author_type <> 2'
An error occurred while upgrading the schema:

Can't locate object method "no_build_indexes" via package "MT::ObjectDriver::DBM" (perhaps you forgot to load "MT::ObjectDriver::DBM"?) at mt-upgrade30.cgi line 366.


ora...sono andata a vedere sta linea 366:

MT::ObjectDriver::DBM->no_build_indexes(1);


cosa devo fare?????
