I believe their was a recent update on premium? (last day or two?) I updated,….but TODAY, found possible problem with secondary menu Social Icon Avatars, twitter, you tube, linkedin…..the ICON picture is GONE ON DESKTOP— NOT ON mobile phone.
Any help appreciated https://www.thesoundadvocate.com/
as Tom said it looks like a caching issue – when you’re logged in the Plugin will be generating the correct code – whereas on your server it delivering a cached file that is ‘broken’ – clearing all plugin and server caches may fix the issue.
