A customer installed the DotNetNuke 7.0.6 APS application into their PA subscription. When they log into the DotNetNuke admin interface and try to add new or existing module the following happens (depending on IIS website security settings):
- Popup window with prompt to enter login credentials appears endlessly
- Nothing happens, admin user is just being returned to the current page
The problem affects also standalone installation of the DotNetNuke application (installed not via APS application).
Adjust the web.config file of the IIS website where the DotNetNuke application is installed to resolve the issue:
- Backup the web.config file of the affected website on the corresponding IIS server
- Open the web.config file in editor
<system.webServer>section and add the runAllManagedModulesForAllRequests="true" attribute to the
<modules>tag like in the example below:
<system.webServer> <modules runAllManagedModulesForAllRequests="true"> ... </modules> </system.webServer>
Refresh the admin interface of the DotNetNuke application in browser or re-log into the application
The problem is caused by the issue in the DotNetNuke application itself.
