Can't assign to roles

Had the same problem. It seems to recognise the default roles only (user 1, authenticated user and anonymous user). For now I just enable it for authenticated users.

Ditto. Same thing here.

I'm seeing the same behavior. I assign BUEditor to new roles but the editor doesn't display unless I assign it to authenticated users.

I had the same problem on the 5.x-1.1 and kinda solved it...
In fact if authenticated is set to "none", your other roles won't have any editor... IF they are listed after "authenticated"...

In order to solve this, in BUEeditor settings, you have to change the weight of "authenticated" to 10 (or wathever) so that it came last...
(and be careful, when I tried to change multiple weights at once, I had some validation issue... so only change 1 at a time...)

weird, but it worked...

The editor isn't displayed when adding a user role while having authenticated user set to none.

This is fixed on dev branch.
A workaround for 6.x-1.2 is to use negative weight values for role sorting. This is because authenticated user role always has a weight of 0 which makes it precede the roles having positive values.

Have the same problem -- can't get it to show for other than user 1. Created an empty files/bueditor folder and set to 777, showed for a moment, then disappeared after refresh. Files set to 777.

Cleared cached data under performance settings, showed for a moment, then disappeared again ater refresh.

Disabled block cache under performance settings, and it stayed after refresh. The form is shown in a block (form block module).
