homepage – Errors in the home page after removing the SEO Checker package under Umbraco V7

I have a problem with which I need help, please.

I had installed the SEO Checker software not realizing that it was only for commercial use, so I uninstalled it, which resulted in the breakdown of the entire site. After deleting all files from the SEO Checker package, all the arrival pages are saved, but the home page is always disabled when using the domain URL.

I uninstalled the package in the back office on Umbraco V7 and deleted the remaining files from the server. Has not touched any other file.

Source error:

Line 4:
Line 5: // Get the basic design parameters from the home page
Line 6: var home = (Home) Model.Content.Site ();
Line 7: var colorTheme = Umbraco.GetPreValueAsString (home.ColorTheme);
Line 8: var font = Umbraco.GetPreValueAsString (home.Font);

I was expecting the home page to reappear like all the other pages after deletion, but the real result is that the homepage only works when you add / home to it. 39, URL of the domain.

I would appreciate that someone can help me because I am not an expert in this area.
