In loading v8.1 on a Windows 2008 32-bit server, I could not get the web client to run. Before getting to the login screen, it would throw this error:
HTTP Error 500.19
The requested page cannot be accessed because the related configuration data for the page is invalid.
The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration
Tried a few suggestions from support, but it still failed. Applying SNC02, Web Core 02, and Web Model 01 did not fix it either.
This web.config modificaiton fixed the problem.
I added the "sectionGroup" as specified in the article inside of the existing "ConfigSections" in the web.config.
