Help - Wordpress Blog crashed!

Hello,

today I changed the nameserver of my host to the Cloudflareserver.

Now my whole Blog is crashed with an error:

I can´t do anything on my site.

Here is the error:

Warning: Cannot modify header information - headers already sent by (output started at /www/htdocs/w015c695/mysite.de/wp-config.php:1) in /www/htdocs/w015c695/mysite.de/wp-content/plugins/http-security/include/http-headers.php on line 49

Please anyone can help me!

I’m not sure this error was caused by changing the nameservers. Make sure the DNS entry for your site is correct in Cloudflare. This sounds more like an error in a php file or plugin similar to: http://www.wpbeginner.com/wp-tutorials/how-to-fix-pluggable-php-file-errors-in-wordpress/

Please stick with the original thread (no need to double-post). Someone already replied there.

I htink his post(s) got caught in our filter and I released both (should have closed one as duplicate… my bad)
