I made a test blog yesterday for my workplace, and I added one of my mentors as an admin. She accepted the request, made an account, and was able to access the blog (dashboard and all) without a problem. However, today, I noticed that her username had disappeared from the "All Users" list, even though the user-count on the top of that page still included her. Now, she cannot access anything or change anything on the blog, and on her own dashboard under the "My Blogs" section, the place where the blog's title should be is completely blank.
I thought about removing her from the blog and then re-adding her, but again, she doesn't show up on the "All Users" section, so I can't even do that. Does anybody have a solution?
The blog I need help with is uwadvance.wordpress.com.
