There's a thread I've previously posted on that I can't post anything further to. As you can see in the screenshot, there's no text entry box. I can attach an image, but if I try posting just that I get an error due to no message.
I've tried in Chrome, Edge and Firefox with the same result. On all other threads, I get the text box and can post normally.
This is the thread I'm having the problem on.
