I've successfully installed and configured the Wysiwyg module with CKeditor. However, it keeps disappearing. First it disappeared when I enabled another module (cannot remember which, but thankfully it wasn't necessary so I could disable it again). I was just lucky to figure that out.
But now it disappeared again, and I don't know what happened this time. I didn't install any new modules.
Any ideas why this is happening? Is the wysiwyg module too unstable to use? If so, what's the alternative?
The issue keeps coming back, but I have discovered something new: if I disable a module (and optionally enable it again), apparently pretty much any module, then the wysiwyg editor appears again(!)
So it seems any change in the modules installed brings the editor back. I have only tested this in localhost, if that has anything to do with it.
