Error when replying or posting new topic

Does anyone else consistently get a timeout error when replying to a post, or even posting a new topic? Whenever I do, I get the "workng" icon on my screen, and then eventually a server timeout error comes up. (Image attached)

Once I see that, If I navigate back to the forum, my post is there. But the error happens every time, lately. (I don't post that often, so it could just be coincidence)

Just wondering if I've got something going on in my browser I need to chase, or if this happens to others.

Thanks.

P.S. Edit 1: Did it on this post.

Edit 2: But not when I it saved my edit.
