Re: wp-signup.php is a blank page
JJJ, the code that Xevo posted ( and I posted in another thread ) IS more effective and also is more correct, because you’re relying in that there’s no output before the signup_header action. Your code was the first thing I tried when I had the problem and, in fact, it didn’t work on my setup.
There are no conflicts because the init action is executed before, so the signup_header action won’t be called.
