Login page adding URL redirected page show

Good Evening,

I am baffled by the following

I have created a login section within my site.

the issue is when I log in the URl adds the previous page

so

http://www.crieffhighlandgathering.com/spectators/?page=login

should go to the user updaste page welcoming the user

www.crieffhighlandgathering.com/spectators/?page=userupdate

but adds the last page to the end.

http://www.crieffhighlandgathering.com/spectators/?page=userupdate?page=login

I am using plugins to access each page and the only one that i am having problems with is the login page. All the others work as expected

user name = demo@demo.com
password = demo

or you can create your own. I will be deleting before I use this live

Thanks
Andy

Can I see your copy of the page authentication.php? I'd like to see what version you have and check if it might be causing the issue.

Hi Ray

Please see attachment as requested

This page looks correct. Is it possible you haven't uploaded it recently?

I'll need FTP information to debug further if uploading this file doesn't work.
