youre not closing the other mysql query for the membership script.

however your membership script is being opened, something like so:

$connect = mysql_connect($DB_SERVER, $DB_USER, $DB_PASS);

the query needs to be closed:

mysql_close($connect);

the above is just an example.

I think that is right, because that only started happening since I switched hosts, and the new host is about to upgrade their system with a main point that their connections aren't closing. So that little function you suggested, do I put that in the "_main" page for now until they upgrade?

you put that inside or within (at the end [when its done doing what it needs to do], obviously) whatever script you are using to open that OTHER database..

"The code is being placed in the custom/_main.php file."

Just append the added code to close whatever connection its making ..
