steampwr8, thanks.
Have just reinstalled latest version of forum software, hopefully all OK now.
1) For those like me whose post text box scrolls off right of screen, delete your internet browser's history/cache/cookies, if you are using Microsoft Internet Explorer 9 like me, when you go to delete, ensure you click off the "Preserve Favorites website data" button at top of delete options page (duh to me).
2) For member's post counts, we used to have 1 (few posts) to 5 (lots of posts) little cheese wedges, these are now squares, I'll fix these tomorrow.
Please report any other bugs in this thread, thx!
