Hello
I have finally installed Rank Math on to my website.
However, I received these two error messages:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'wpfresh4_filter_robots' not found or invalid function name in /home3/fledge007/public_html/wp-includes/class-wp-hook.php on line 286
Warning: Cannot modify header information - headers already sent by (output started at /home3/fledge007/public_html/wp-includes/class-wp-hook.php:286) in /home3/fledge007/public_html/wp-admin/includes/misc.php on line 1126
My site is hosted by Hostgator
Wordpress ver: 4.9.8
The site is in an early stage of setup.
The plugins that are installed:
Akismet Anti-Spam

Most of these plugins are installed for test purposes only.
