When I open wordpress.com, the screen appears as 'reader' and all the blog posts are diminished in size and centered in the middle of the screen and the text is too small to read. The same holds true if I click on 'my blogs' or 'stats'. Only if I pick a blog to read does it then open up in full screen. Wasn't always like that. Suspect I have altered something along the way that caused this. Any help appreciated.
The blog I need help with is oldmainer.wordpress.com.
