I am using JCE 2.5 with Joomla 3.9.8 Stable.
I have 2 user groups; one is a super user and other is frontend user.
The editor is loading fine for super users, but for frontend users the toolbar of editor is missing. It was working well and suddenly disappeared, not sure what was the contributing factor.
I have checked all the settings of editor and user group and everything is fine. The editor is enable and set as the default. I also tried adding JCE editor under the basic settings of the user but nothing helps.
When I click on the "Toggle Editor", it just hides the grey section meant to load toolbar below is the image.
