I have got a database error for 2 days; My hosting company can't find out what is the problem since the problem occurs when one of the members perform an operation ( I don't know what or when the operation is perform). Boonex says That they only they only focus on software development and I should find the answer here in the forums

You have posted your Facebook API and secret key, try to edit and remove.

Your site is working fine on my end.

Your getting tons of spammer accounts, bots, you should split your join form into two pages or do the other suggestions here in the forums to stop them.

Perhaps another member will be able to help with the error.

Edited OPs entry to remove all sensitive data and left the original error.
