Users makes a request to cpaddons to install phpbb and we go to the "moderate cpaddons" and approve it. No errors pop up and it appears to be installed, however if you
go to their account adding the folder path it comes up with this error:

Fatal error: Cannot instantiate non-existent class: sql_db in /home/userxx/public_html/folderxx/includes/db.php on line 60

Any idea what this is ?

Systems runs: Freebsd 6.2 / Perl 5.8.8 / Cpanel 11
