@mark-coniglio hi Mark. At this time I am not aware of any regression with the mentions plugin, which would usually point to some sort of configuration error.
Do you see any errors on the client side, in the browser dev tools?
Sorry, I have problem.
Ordinary users do not have permission to upload video, what can I do?
@bgdztft In the category privileges page, you will need to enable the Upload Files privilege.
I don't what is the reason behind it. It is better for you to contact site admin to know about it.
@florencewillburn thank your answer, this problem need edit code, It doesn't matter to the administrator.
@julian thank your answer.
I too have problem with uploading and could you find a solution for this
