OK, I have spoken to Ross. This means that the WP function wp_remote_get
is not working for our plugin.
This means that the process has to be completed via Ajax. It can also be caused if you have disabled caching via the Search & Filter plugin main admin global settings page, but I assume you have not done that?
At this time, there is not much that can be done about it; just leave the page open, we hope to improve the functionality of this in the future.
It might be worth checking a couple of things though. If you know where to find the main WordPress wp-config.php file (in the WordPress root folder), look for a line that starts like this:
define('WP_CONTENT_URL',
It should look like this:
define( 'WP_CONTENT_URL', 'http://example.com/wp-content' );
But some sites have this:
define('WP_CONTENT_URL', '/wp-content');
where the URL is missing (or the http should be https).
Also, does your server have a firewall, like CSF? It might need to have a whitelist rule added if you have (but I do not know what the rule would need to be, but your host might).
