Solved! My webhost made some changes in firewall.

Thanks for help!

I solved problem with warning message. But now nothing happens when I ‘save’ API key. For about 20 seconds it’s trying to save and then nothing.

Edit: I disabled all plugins except this, and after I click ‘save’ it’s loading for about 20 seconds and then nothing happens.

When I disable Better WP Security in I save API key I get this message:
Warning: Cannot modify header information – headers already sent by (output started at /home/viking/public_html/wp-config.php:95) in /home/viking/public_html/wp-includes/pluggable.php on line 896

It’s problem with EU Cookie Law Compliance plugin. Thanks for help!

Thank you, I removed spaces. Nothing changed with permalinks. How can I remove ?zsid=173157858cb22a9 from the end of link?
