Ok Ian. I tracked it down. Here's the scoop. It was coming across a post that had a TON of graemlins in it. You also have quite a few graemlins in your 6.5 board. So when it went to undo the markup for these it was basically choking. I redid the code a little bit on this and it seems to be working fine now. The altered code is still on your server so if you go ahead and start clean again you should be good to go

Thank you - will delete the tables and start again.
