Cannot get Rid of Site offline

Hi
I hvae tried sending mesages, but since installing this plugin, I cannot get my description when i post my url to say anything than SIte offline.
I unistalled the plugin, deleted it from teh website, cleared the cache and 3 months later every time I put my URl in on a page or link it shows SIte Offline.

I hve seen multiple posts who have all suffered the same fate. and had no joy from the software developers who say “it takes a few days for google to update”

Its been over a month and `i think this is the worst plugin. cannot change our desription to be anythign other than “site offlline”

I owuld never recommend this plugin to anyone
