Unfortunately I can’t fix it, reinstall and playing around with the configurations didn’t work either: it makes no difference whether I use the Tag Editor or not. The backend seems to work correctly. When I use the Tag Editor the inline code snippet is green exactly where expected. But when previewing the code in the frontend the above error accurs.
EDIT: I observed that on your own Demo-Site the error occurs as well. Please have a look: https://aksandbox.webege.com/?p=79
From that page i get this output.
