pgn viewer not working - Chess Forums

I've noticed recently that oftentimes the pgn viewer glitches out and looks something like this: when instead there should be moves. When I click on the analysis button it just redirects me to a blank analysis board. I'm pretty sure it's not a browser problem. Any help would be greatly appreciated--thanks!
