I had a similar issue in the shifter thread I started yesterday. On my initial post, I had a photo attached. When I clicked the post button, it went to a white screen and would not accept my thread. I tried that two or three times. I tried one more time without the photo, and it went right through without issue. So, I went back and added the photo to that post, and it screwed it all up. Now when I click on my thread, the page comes up but without my post. I messaged Glenn to delete the entire thread, and have not gotten a response as of this morning.
