[Moin-user] Strange error message

[Kai Jaeger]

Today a user of my wiki sent a screenshot. It's telling this after
clicking "Save" in the text editor:

"Please use the interactive user interface to use action action"

His work was gone although he had pressed "Preview" several times
before he finally pressed "Save"; It was a completely new page.

This error message is complety rubbish of course. How can one use a
non-interactive user interface to edit anything?!

Advice and encouragement is welcome ;)
