This website used to work previously but recently the published version stopped working due to this error. As far as I can tell, the only change was installing iTextSharp and iTextSharp xmlworker through nuget.

I have tried, without success:

1. giving modify permission on the site folder to Everyone
2. checking the web.config file, and using an older version of the web.config file (from when the site worked).
3. uninstalling iTextSharp and iTextSharp XMLWorker

The project still runs without issue from Visual Studio.

Answer 1

This is solved. The error was caused by the folder name not matching the path for the virtual directory. Oh wow I feel dumb.
