I have a website and suddenly it displays this error when I try to go to the homepage:
Sorry, I need a [url removed, login to view] file to work from. Please re-upload this file to your WordPress installation.
I don't know how to fix it.
The error is due to [url removed, login to view] file missing or changed permission or someone deleted your site. I can check this no guaranty to fix if the files are missing.
