Hi Preran, thanks for your quick respons.
The steps you suggested, i did follow them and they where okay.
I am not new with Muse and am a fist adopter with Muse. But i have this issue.
If so, i can send you the login credentials for this site so you can see witch problems i have for my client using inbrowserediting.

I am not sure I will be able to help you much as I have little experience with this error message.
I suggest getting in touch with Chat support using this link Contact Customer Care Click on Creative Cloud All Apps, and select Adobe Muse from the options.
Wel i did, but then i landed on the community forum sit. no way to chat....
Actually this not a Muse issue but has to do with in-browser editing backend.
They can help you with this however, you need to log a case with them through this link - https://feedback.inbrowserediting.com/#contact-us.
Hope this helps.
