Hey Mahboob - please see attached jpg. I am getting this error again when I click on test emails - so I am still not launched: 

[an error occurred while processing this directive]. 

I found some possible fixes at:
(1)  https://wordpress.org/support/topic/an-error-occurred-while-processing-this-directive-after-wordpress-4-8-update/  and 
(2) http://www.jodyhatton.com/fix-an-error-occurred-while-processing-this-directive-in-wordpress-by-setting-file-permissions-with-this-recursive-automatic-php-script/
It seems all DIRECTORIES need to be set to 755 and all all FILES to 644. (Go to yourdomain.com/php_permissions_755_644.php) 

Also, there is a backup copy in one of the folders named "OLD" that may be part of the problem if php files there get searched so let's just delete it.

Please fix this for me ASAP. My email links MUST work before I start selling. Thanks, Patrick
