I have reinstalled and the prior problems re-appeare but the priot solutions do not work.
The Home page shows a reply box. As suggested last time I have unchecked everything related to blogs both on the screen options tab and on the settings pages. It remained.
Next I deleted the home page. The site was no longer displayed, just some user info. Now, as in a previous problem, I can see the site with Firefox but not with IE. I did the F12/ doc Stds = IE(9) but that didn't help this time.
I apologize for recycleing old problems. Thanks for your help.
