Hello. I have two domains on my account.I use WordPress on both. The older domain work fine, but when I try ti log in to the other, I am getting these error codes: Hello!

On the top of the WordPress login page:
"Warning: Cannot modify header information - headers already sent by (output started at /home/miketh8/public_html/ in /home/miketh8/public_html/ on line 415" and:

Warning: Cannot modify header information - headers already sent by (output started at /home/miketh8/public_html/ in /home/miketh8/public_html/ on line 427

Then when I type in my username/password anyway: I get this:
ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.

Even though the cookies have been set correctly.

Like I said, the other domain (with WordPress) works fine. The last time I used this domain I had no problems.

What is going on hers?

Hello, and sorry for the troubles.

The PHP errors that you were getting are caused by trying to modify the HTML headers of a page, after they've already been sent to the visitor's browser by another script.

It looks like the error was also occurring on your main site, and was not limited to just the admin login page.

To fix this for you I moved this file:

To a backup copy of:

That script was requiring this script:

Which was simply using PHP to echo the phrase Hello!, and because it was trying to do this after the HTML headers had already been sent previously by the rest of WordPress it was triggering this error.

Do you know where this posttypes.php script came from? It is not a part of the core WordPress files. If it's a part of the mdportfolio theme then it shouldn't be trying to simply echo out something, or a headers error like that would happen.

Please let us know if you have any other problems or questions!
