When my website moved server from a plesk server to a cpanel server loads of errors occured and I need this to be fixed on the website.
I think there all basically the same here is an example of one error:
site : WOW Free Gifts
page : /[url removed, login to view]
ad => 555
Query : INSERT INTO clicks (user_id, click_time, offer_id, pending, approved, approval_time, points, revenue) VALUES (110789, NOW(), 555, 1, 0, NULL, 1, 2)
Error : Duplicate entry '0' for key 1
Sorry a database error has occured. This has been logged and will be fixed promptly
Hopefully you can fix this similar errors are on about 10 different pages on the main website and on the PhpBB forums the PM system is not working with a similar error.
