Same here. Quick reply shows an empty box that I cannot type in, I am also unable to edit any posts. Tapping edit gives the box but the post is not in it to edit. I have this problem on 2 PCs running Win10 and Win 11. The problem manifests in Mozilla Firefox, Edge, Chrome and DuckDuckGo browsers. Both computers automatically clear cookies on closing the browser. The forum still works on an iPad running Safari or Firefox.
