Html embed disappeared

Hi all,

I embedded a linkedin-follow button in my navigation next to the “Kontakt”-Button. It worked at first and was shown on the published and then disappeared after a few changes have been made (nothing that should interfere, or so I thought). I can see the LinkedIn-Follow in the DevTool but it’s just not visible on frontend. I tried going back via backups but can’t figure out the point it changed because I can only see the embed in the live site. I turned off the ShareThis Button because I thought it could interfere - but nothing.

Can someone help?
