I have experienced this bug too, sometimes the editor won't pop up (and there is no 'enable editor' button either). I wasn't able to trace this bug down yet...
Besides rewrite rules I have seen something like this, and that is either when jQuery fails to load (for OE 5.1+) or if you have some kind of old firewall that filter JavaScript files to aggressively.
I'm having the exact same problem, with 4.3.0 (no ezflow). Suddenly I get an error about not having permission to use ezoe, when before I have just used it. After I clear caches, the editor comes back. I believe it has something to do with eZ mixing roles or policies between siteaccesses, because it usually happens when I'm logged in as an admin on the admin interface and, simultaneously, as a Guest account (without ezoe policy) on the frontend. All other policies seem to work fine.
"After I clear caches, the editor comes back" What change(s) have you made before seeing ezoe gone? If clearing cache could bring back the editor, meaning that some program code might be changed.
I didn't install any new extension nor changed any setting or anything that would require clearing the cache.
I think I just found out where the problem is. The editor disappears after I edit a policy for the Anonymous role (but apparently not after I add or delete a policy). If anyone else confirms it, i'll file it as a bug.
