Firefox 48.0.2, IE 11 both had the problem and still do .
The only way I got here to add this msg was thru my statistics and find all posts.
If I tried to go from the forum home it just was a blank page and I didn't wait more than 2 minutes so I don't know if it would eventually work or not.
But it isn't right and it just started happening this afternoon.

Hah! Now after I finished the above it's working OK.
