Hello Mark,
Your posts don’t appear to be coming from a different IP address, which means the issue is most likely within your computer, or browser. I would run a virus scan, check browser extensions, and/or try a different browser. We haven’t done anything on this end, but will continue looking into finding anything further here. Please let us know what you find on your end. I notice the bottom links don’t show up on your most recent posts, did you change anything on your end?
Abraham
