Not able to save or create new product or category

Not able to save or create new product or category

Hey Guys,

I suddenly found out that I am not able to change and than save category or product. I can go to the detail page, but when click on "Save" or "Save and Close" nothing happens like if the link was inactive. Even the close button is dead.

Anyone knows what to do?

Thanks

Just solved this:

Default system Editor in global configuration must be set to TinyMCE
