Problems posting stories.

Hi. I seem to be having a wee problem posting my stories. I get as far as 'preview, but when I press save, the page crashes and I get a message 'Error number 502 Bad Gateway, This happens every time but when I go back to basics the main home page opens without a problem. I have obeyed Erin's instruction not to try to repost old stories like Mermaid 111 and 'No riches' after her scolding me but this was a new chapter. I don't know what's gone wrong cos' other people seem to be able to post stories.

Am I still on the naughty step?
