Answer 1

It sounds like the query that is causing the error happens when something specific is called. This could mean that when the query is called, you aren't connected to the database with the correct username/password.

Try to ensure that you are definatly connected, use or die(mysql_error()); at the end of all your query variables to debug them.

Also, use the following two lines at the top of your php file:

ini_set('error_reporting', E_ALL);
ini_set('display_errors', 1);

That will show you any little php errors that may occur within your class/file which you may not have picked up before.

If your still having a problem after this, please post your PHP code and I will take a look at it directly.

Thanks!
