I am trying to update my DNN version. Downloaded, extracted and copied the update package in my DNN site root. Now when I'm trying to access the ~/Install/UpgradeWizard.aspx page (visiting my site already redirects to that page), I am facing JS errors in console. Most of them are "Uncaught syntaxerror: Unexpected token <". I didn't change any tag in that file.
All the CSS/JS/Image resources are not loading. Tried even to specify the absolute path, but didn't help (maybe trying to redirect...).
Please, help me.
