WordPress MU

Hello Folks,

I am having problem with publishing new posts in my blog since my server has been upgraded to php 5.3 (this is what the hosting service is claiming). Whenever i press the publish button, instead of getting the post published, the 404 page opens saying page not found.

Looking for your expert help on this issue.

Thanks
Shibli

The WP 404 or an apache 404 and which page is it reporting that can't be found?

Is there anything in your php error log?

wp 404 page saying 404 ERROR - Please return back to homepage

mod_rewrite not working again.

Tell your host that your permalinks aren't working since the upgrade. They'll know what to do.
