Plesk has some bugs if you aren't careful. And it doesn't always 'see' changes you make thru shell either. We ran in to that just a few weeks ago and our tech was pulling his hair out trying to get it all sorted to work right.
Ensim looks abit confusing with all those icons as far as I am concerned. And the test one I looked thru seemed to be missing some things that would be needed on some sites.
