pdo_msql.so

You misunderstood a bit InsiteFX.

You have to check if the line

Code:

extension=pdo_msql

exist and is activate in the "php.ini".


If you see

Code:

;extension=pdo_msql

that's means the module is deactivated.

But I also suspect a typo somewhere because it's seems very close to the module "pdo_mysql" with a Y, so I don't know.
