Anyone experiencing slow backend lately please update your /lib/php/includes.class.php file with the code provided below.
It seems that our third party Google fonts provider's site is down and thus makes impossible loading content from it.
Find line 237 or 250 (depending on your theme) from includes.class.php file located in /lib/php/ folder of your theme.
and instead of
$googlefontsSeraliazed = wp_remote_get("http://phat-reaction.com/googlefonts.php?format=php");
save your file as:
//$googlefontsSeraliazed = wp_remote_get("http://phat-reaction.com/googlefonts.php?format=php");
This is a quick solution for now. Please expect theme updates to completely solve this issue.
Should you require custom support to perform this operation please open a private ticket containing your hosts credentials.
