I have a wordpress multisite installed, with many sites running off of it.
This morning I found that my main site that all of the custom premalinks no longer work and send to a 404 page.
They were all working last night.
They work on all other site on this multisite.
Nothing changed from last night. I reset the permalinks via the admin area, still dont work.
But if I use any of the premade permalink structures it works fine.
Any thoughts on this?
