Nothing but trouble

I wanted to make some updates to my site, and another plugin wasn’t satisfying my needs, so I tried this one. Oh my goodness what a nightmare!!! It looks nice from the Admin CP, but when you go to the site, it’s covered in ads!! Even after changing the background image, it was still covered!! This obviously caused me to inactivate the plugin and delete it. This still didn’t help! Some how, it still leaves the page unchanged and now I’m left trying to fix the site instead of doing major updates!!
