Hello,
unfortunately I have no more possibility to edit my page.
After I tried the new function with the animated banner I can't do anything on my page.

Disabling browser extensions, incognito mode, clearing cache and restarting the router have brought no results.

Would appreciate some quick help.

Kind regards
Dani and Sarah
