I used an ad-plugin on a GD website, and when I removed it for whatever reason the editing of the website was altered and I can no longer make changes I want. So the entire template is messed up and I wanted to remove it.
I have removed the template in several different ways, waited an hour, and every time when I re-install it it pops up just the way it was before deleting. During deletion the main website was set to the blockstrap template. On the messed up template resetting the pages, archives and so on does also not work.
 
So somehow the template I want removed is not deleted. After deletion it is nowhere to be found by File Manager of Filezilla, so it looks as if it is gone. But somehow it keeps coming back.
 
Would any bright mind have a suggestion on how to eradicate this template so I can re-install in in the default settings??
