Can you screenshot the error? It could be a couple things.
I can’t make a screenshot at this moment, but the message i get is: ‘Blocked’ and a white screen. I did research on the internet and i found that my account could be blocked because of hack attacks of other people and therefore the account is locked. Is it possible to undo this block as quick as possible?
I solved the above problem but when i try to login i get a new problem:
ERROR: Cookies are blocked due to unexpected output. For help, please see this documentation or try the support forums.
And the following messages
Warning: Cannot modify header information – headers already sent by (output started at /customers/9/0/8/frdrotterdam.nl/httpd.www/wp-includes/functions.php:1) in /customers/9/0/8/frdrotterdam.nl/httpd.www/wp-frd.php on line 414 Warning: Cannot modify header information – headers already sent by (output started at /customers/9/0/8/frdrotterdam.nl/httpd.www/wp-includes/functions.php:1) in /customers/9/0/8/frdrotterdam.nl/httpd.www/wp-frd.php on line 42
FYI, you couldn’t show the image because you did this:
<a href="http://postimg.org/image/qz10zuy69/"></a>
And if you can’t tell, that’s a link with no content. 😉
That blocked error is not a WordPress error, however….
