I am working on some customized themes and when they are activated I cant log out, it goes blank. If I get rid of all cookies (being logged out) I cant log back in. The login.php shows, but when I've filled out the login form and hit the login button it's just a blank page showing.
As you probably figured I've tried everything I could come up with, that including googeling for days and trying all solutions I've found. There are no empty lines or spaces anywhere, I've disabled all plugins, I've even tried to rewrite one of the themes using twentyeleven as base. I'm out of ideas where to look.
My theme is not an ordinary blog theme but suppose to become a website. All other themes I've tried is working, including some free themes and twentyeleven. I can log in/out when they are enabled. The strangest thing is that everything worked just fine yesterday and today it doesn't, I thought rewriting it solved the problem, but no.
Any ideas where to go from here?
Hoping for answers before I go bald, Bellisia
