Visitors Unable To Register

[Hendy]

Visitors to my site are not able to register, the page to enter the birthdate comes up but then when it goes toregister.php?do=checkdate it just goes to an error page.

Any advice would be appreciated.

500 errors are server errors, so it would help to find the actual full error from the server logs. Your host can help with this.

However - a few questions...

1. What version of vBulletin are you running?
2. What version of php is on the server?
3. Are there any add-ons being used?
