If you are encountering an issue with new DNN 7.1.x installations that causes most of DNN's URLs to result in 404 errors then please try to following fix.
- Within your site's web.config file locate the opening tag for the "modules" section of the web.config file which is:
"<modules>" (without quaotation marks)
- Then modify it so that it reads as follows:
"<modules runAllManagedModulesForAllRequests="true">" (without quotation marks)
- Then save the web.config file and restart your site. That should resolve the issue and allow your links and pages of your new DNN 7.1.x installation to resolve correctly.
Please note that this seems to only be an issue with DNN 7.1.x versions of DNN when ran in IIS 7.5. Different DNN versions or running them within IIS 7.0 shoudl not encounter this same issue.
