lol, I'm trying little tips and various edits two days now, and today I decided to write you for help.
Immediately, after I posted the request I came up with the new experiment. I turned my site to the default xoops cube theme and I saw it works.
I'm using a custom css template as theme.
Hmmm, so now whats is going on? What is that the custom theme need to support and enable the fckeditor?
