Meta Name and Base href

Just recently when I compose a new web page there are two variables set Meta Name and Base href.

When they are set; the page works fine on the development server but once the page is uploaded to the live production site these pages break. It appears as the path gets changed and thus any future page fails also. I tried removing these lines but they reappear once the page is saved.

Can anyone tell me why these two variables are set? Thanks Jim
