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 126.96.36.199 at my MaxCDN account
- I whitelisted 188.8.131.52 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?
