This AM I update logged in an updated two plugins (I didn’t note which ones, but I only have less than 8 plugins installed). I can back a while later to make some posts and realized I had a problem. My Add Posted Link button sends me to a 404 error page. I can still get to All Posts and Add New. I also noticed that sometimes when I clock on Dashboard it sends me to the 404 page, sometimes it goes to the dashboard.
