12383	Permalinks Fail After Adding New User	shodezignz	ryan	"2.9.1 - MU

Have Main Blog and 9 other sub blogs
Using Plug In - WordPress MU Sitewide Tags Pages - to pull posts to main blog
To make problem
Go to Site Admin panel
Users - Add new user on main blog
Go to Blogs under Site Admin Panel
Add user as author to each blog
Check Website and see that posts no longer link back to post

The way i have to fix it is go to each blog and save permalinks (not changing or even clicking anything just clicking save permalinks) and links on site work again.
