I was installing a custom look in SharePoint 2013 on-premise and after applying the custom look, my home page doesn't load and showing me the following error. Please help me to fix it,
Could not load file or assembly 'Microsoft.SharePoint, Version=16.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.
