I can't use WP Smush Pro anymore. Anytime I try to smush images I get this error:
Request failed Site URL not accessible
What I already did to try to solve the problem:
- I whitelisted 18.104.22.168 at my MaxCDN account
- I whitelisted 22.214.171.124 at my HTACCESS inside wp-admin to allow access to the folder
- I installed the plugin and logged in with my WPMU DEV Premium credentials
What did I forget to check?
