Users setting problem

I was adjusting some of my Users settings for one of my WP blogs (I have two). I noticed that I was listed as both admin and as a subscriber (not sure why?), with the posts listing (# of) on the right side showing a certain number for me as admin and a certain number for me as subscriber, so I transferred those to show under my admin name along with the others as all posts have been done only by me, and I am the admin.

I then deleted my subscriber name, as I thought I didn’t need it, but now there is no name at all showing up under my post titles and (worse) I also now can’t access a lot of my admin settings such as hosting panel, appearance, plugins, users, settings, etc. It’s like I have restricted access now for some reason, although I’m still listed as admin. I tried logging out and back in again too, but no difference.

Not sure what I did or how it can be fixed?
