- Fatal error: Class 'PDO' not found in /files/phpmysqlautobackup_extras.php on line 203
in version 1.6.3
then this is a general error due to the PDO extension not being loaded by your web host.
Complain to your host that PDO extension should be loaded in PHP.
Or you could use:
http://www.seiretto.com/web_hosting/php_hosting.php
as all the hosting accounts include PDO.
All the best
