Can't See My Own Posts

This happened about...10 minutes or so ago. I posted in Shadowfang's Pokemon Mystery Dungeon RP, but I couldn't see my own post. I tried posting again; I couldn't see it, but it was now double posted and everyone else could see it. Then I logged out than back in. I could see it then, so I deleted one of the posts, but now I can't see it again.

Update: I think I've found the problem. At times the sid= part of the URL kept vanishing, but hopefully it'll stop. Thank you for any mods that read this in case you fixed it.
