Publish to web not working

Does publish to web work? Doesn’t seem like it. Also on older file that i never stopped publishing, gives the same message.

What message? I see a rectangular plate with four corner holes and “58b” on it.

Seems to be working again, except that when i load the project and click “Share”, it doesn’t show that it is shared. So do i have to write down now which ones i shared, share them again and then press “stop sharing” in case i want to stop sharing? Or can i manage my shares somewhere?
