do i need to upgrade? wouldn't see how this would affect signing in or does it? please let me know as i need to fix asap. thx

You should upgrade simply because a lot of bugs were fixed in 5.0.4.

As for the error... what is in your error_logs (if you don't know where they are, ask your host)? You can also go to both config.php files and set debug to true ($config['Misc']['debug'] = true and then see what the debug error is on that page.

That error has nothing to do with the error in vBulletin. That is saying a custom 404 error page wasn't found, not a big deal.

You should check your PHP error logs.

Would suggest you upgrade to 5.0,4 (backup first) that may just fix it.
