login problem after delete

I deleted one of my test accounts, and then these showed up:

at home page:

Warning: Cannot modify header information - headers already sent by (output started at /home/******/*******.com/home/templates/tmpl_uni/scripts/functions.php:513) in /home/******/*******.com/home/inc/design.inc.php on line 488

admin login:

now my test accounts and admin can't login at all...

thanks in advance :)

Okay... can you provide an URL to your site. And you just deleted "test members"?

thanks. it's working now. I just reinstalled everything 

Sometimes in the testing stage that is the best solution :)
