The error log shows a line like the following:
Http-Error 500.19 Module DynamicCompressionModule this configuration can't be used because it is blocked.
The reason for this is in the web.config file provided with the forum software. There is the tag:
<urlCompression doStaticCompression="true" doDynamicCompression="true"/>
So, the software comes with a "gzip/deflate compression" enabled setting.
However, in some server configurations this particular setting is set NOT
to allow making changes on this attribute at the Application level configuration file.
You have to allow this by editing the applicationHost.config
file located under \windows\system32\inetsrv\config
. Open the file with a text editor andsearch for:
<section name="urlCompression" overrideModeDefault="Deny" />
change "Deny" to "Allow" and you can proceed. Alternatively
, you can remove the urlCompression line in the software's web.config file.
