This was the first time that I went into Admin to view and edit my pages. The page navigation on the index page has worked fine. I needed to find one page and see how I coded it. So, I went to Admin and Manage - Pages and only 22 showed up with the last one missing the Delete option.
I then filtered by each type and was able to find all my 83 pages. I guess it could be a plugin conflict after upgrading to 2.3.1, but I don't know.
Does anyone have any idea what could be wrong?
Thank you, jim
