I am using joomla 1.5.23, cb 1.4, gj 2.3 and jce 1.5.7.11.

There seems to be an interaction between gj and jce.
After changing something in gj editor (html or WYSIWYG), in frontend I've lost my jce editor only a blank side (like for plain text), but I cannot save changes.

When I open groupjive disable groupjive plugin, then jce and saving works in frontend. When I enable it again (without changing anything), jce and saving are working.

What do you mean by GJ Editor?

In groupjive configuration I have on different places the possibility to choose Editor between plain text - HTML text - WYSIWYG.

Could you please be more specific as to exactly where this happens?

I know now a bit more:
1) With groupjive disabled (picture 2): When I login with cb_login in frontend, and try to edit an article, I can edit and save it with my jce editor (picture 3).
2) With groupjive enabled (picutre 1): When I login with cb_login in frontend, and try to edit an article, I can't edit it (there's no editor and I can't save changes in article (picture 4).
3) When I stay now logged in, but I enable in another window the groupjive plugin (picture 1), go back to the first window with the frontend and try to edit an article, I can edit and save it with my jce editor (picture 3).
4) But when I logout and login newly, then it's the same like 2)
I made all these with this configuration (picture 5)

I also tried with configuration set to plain text. It's the same)
I didn't try with configuration set to html text.

I continued testing and found that it's only the problem of jce. With TinyMCE this problem doesn't exist.
So I contacted the JCE Forums. It seems to be a problem inside JCE.
