Login Problem Ajax Error with Userpro

Hi dear Community, it’s me again… 😛

Well unfortunatly I have again an other problem with the theme.

Well this time it’s a plugin with the team. I’m using the plugin UserPro with the theme.

When someone try’s to login he gets the following error:

error in jquery.ajax while submitting a form: invalid character

This is only happining with this theme and on all the others it’s working fine.

I’ve you need the plugin I can surely provide it for test purposes or grant you access to my webserver.
