Signature Error Messages - vBulletin or Host problem?

[Masamune.]

I'm encountering a problem when users update/preview signatures. The following error code reads at the top of the page:

Warning: getimagesize() [function.getimagesize]: URL file-access is disabled in the server configuration in [path]/profile.php(2283) : eval()'d code on line 20

Warning: getimagesize([COLOR=#ff0000]*file name here for example*[/COLOR]) [function.getimagesize]: failed to open stream: no suitable wrapper could be found in [path]/profile.php(2283) : eval()'d code on line 20

It doesn't seem to actually affect anything but I'd rather not have a bunch of error code flashing at the top of the screen when people want to edit their signatures. Is this a vBulletin malfunction or something I need to contact my host about? If so, what exactly will they need to fix?

Many thanks,
Wayne

Line 2283 of profile.php in your version is this:

[FONT=monospace]    ($hook = vBulletinHook::fetch_hook('profile_updatesignature_start')) ? eval($hook) : false;[/FONT]

This means a plugin using the 'profile_updatesignature_start' hook location is causing the issue. You need to go to:

AdminCP > Plugins & Products > Plugin Manager

...and find what plugin is using that location then speak to the author for support with this.

Thank you, Trevor. Turns out it was a problem with this hack - HS External Signature Limiter.
I'm not entirely sure what the malfunction is but I've disabled it for now.
