As far as my setting, we have Custom Community Pro, Permalinks were set on post name. I had custom slugs for the main pages. Things were working.
When I went to edit the index, which is my main welcome page. I go to pages, I click on Edit and it brings me to some other post. If I try getting at it in other ways (view the page and click the edit page link at the top) the same thing happens. A few of the other pages have this problem as well (they each go to different post but each one always goes to the same wrong post. (note Pages are going to Post) I have had this problem before with this site and I can not remember how I fixed it or worked around it.
I can change the overall permalink setting back and forth to any of the options and there is no change in how it fails or the wrong pages it sends me to.
Worth noting that if I view the post it sends me to and click Edit Post, it works fine.
Also, several of the pages go to the correct page when I attempt to edit them.
I don't even know where to look to fix this, so any help would be great!
