getting error using security assist

I just bought the Security Assist and setting up with Wizard.

I try to register and i get an error:

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /home/xxx/public_html/PROJECTS/test/users_Registration.php on line 8

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /home/xxx/public_html/PROJECTS/test/users_Registration.php on line 9

I then move the <?php require_once('Connections/main.php'); ?> to the top on the page and then i get a error:

Warning: Cannot modify header information - headers already sent by (output started at /home/xxx/public_html/PROJECTS/test/users_Registration2.php:25) in /home/xxxx/public_html/PROJECTS/test/users_Registration2.php on line 77

Please help - Database connection working for for regular insert and update with Dreamwevaer and testing the connection come back successful

o.k. i found something out when i have the DMXzone.com extension - Universal Form Validator PHP

the error occurs when i remove the extension everything works - why is this can't i have both installed at the same time - i realize i can't probably use the dmxzone extension to validate webassist forms (can I?) but to have to uninstall it? why is that?

The second error that you saw after moving the connections include to the top is a result of have an extra space between php tags. Make sure to not have any new lines of spaces between php tags.

I'm not sure why using dmxzone will break the registration page. But it could be that you just needed to move the connections include to the top.

If you are still seeing the error please post back with your registration page to see where the issue is coming from.

fixed thanks
