Description
When viewing a Flowtime site or page, you intermittently receive an HTTP error 403: Forbidden.
Cause
Generally, the error occurs when a request from an authenticated user that does not have local admin privileges results in a failed read of the /BIN
directory by the impersonating w3wp.exe
file (IIS worker process for ASP.NET) process. This behavior is associated with insufficient permission to the temporary /BIN
directory, where ASP.NET assemblies are Just In Time (JIT) compiled.
Affected Versions
