Textbox to write reply in a forum is not showing

[Jose Araya]

Hello,

An admin user in our company's forum can't reply to topics posted in there. The space where the text box should be has disappeared and has been unable to comment for the last few days.

I have done a reset to the values of the toolbar that is present in the textbox, I removed and added again the access that the user had. We tried accessing the forum from 4 different browsers and in different devices, but it always is the same result.

Are there any known issues or solutions to this kind of issue?
