Drupal 7.x

Drupal makes automatically url's like these:

I think I did something accidentally I was not aware of. Unexpectedly, my Recent Content block which is in the left hand sidebar of a Pixtures Reloaded theme, started expanding to the right overflowing the sidebar and bleeding into the main content. It only happens when logged in and all the recent content is mine. I noticed that the edit and delete links are listed with each recent content listing. I don't think those were there before.
