Seems throughout the day my blog seems to show 404 page errors with no pattern. I have to manually change the permalinks from /blog/%scategory%/%postname%/ to default, then back to /blog/%scategory%/%postname%/ in order to fix the permalink issue.
This has been a problem for us for the past six months, and our site gets 10k views a day. While that is not a lot, it does give us a huge problem when at certain periods of the day we have a huge issue where none of our Posts work, yet Pages continue to work fine.
I have extensive conversation on this issue at this post (http://stackoverflow.com/questions/3506130/wordpress-permalinks-not-staying) where I have narrowed a few things down, and at this point I believe the sCategory Permalink is the issue. I need help understanding what is causing this issue, and more importantly fixing this so it never happens again.
ANY help would be greatly appreciated.
