I am successfully running pligg 2.02. However I am getting flooded with the error message " PHP Warning: Table 'mydbname.pligg_files' doesn't exist in /home/websitename/public_html/libs/db.php on line 479 "
There indeed is no table " .pligg_files in my database. Can I add it? What are the datatypes and sizes for the variables?

Please help me, I am so disappointed because i haven't know Adblock Detection Coding for my Pligg websites. So if anyone know about this code please share with me.
