User receives HTTP Error 500.19 - Internal Server Error.
The requested page cannot be accessed because the related configuration data for the page is invalid.
This happens when running Web Suite on IIS 6 or IIS 7.
Usually, it is a permissions issue, or Compression Scheme is ON and the 32-bit web apps do not support compression.
To correct the permission issue:
1. Open %windir%\System32\inetsrv\config\applicationHost.config file in Notepad.
2. Change value from "Deny" to "Allow" for
a. section name="handlers" overrideModeDefault="Deny"/b. section name="modules"
allowDefinition="MachineToApplication" overrideModeDefault="Deny"/
To turn off compression:
1. On command prompt (Run as Administrator), run this command to turn compression off:
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']
2. In case you need to turn the compression on again, here is the command for that:
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /+[name='xpress',doStaticCompression='false',dll='%windir%\system32\inetsrv\suscomp.dll']
