This was my original error:

Fatal error: Call to a member function num_rows() on a non-object in /home4/cultured/public_html/system/libraries/Form_validation.php on line 1122

I thought it was because I didnt have a form vaidation in my library folder. After making one it messed up my login so I took it out. Now I still get this error after trying to test register. How do I fix this? I thought I added the proper links within my autoload and config files, I guess I missing something else. Thank you for the help

@Mekaboo,
Try this instead:

Return ($query->num_rows() === 0)? 0 : $query->num_rows();

Also, you might want to see what value $query->num_rows() is putting out. Do an echo statement. Also, Xdebug might be helpful as well.

Thank you so very much
