I installed the standard dotnetnuke 4.8 about a week ago, and in web.config it has 2 references.
Under <system.webServer>
<modules>
<add name="UrlRewrite" type="DotNetNuke.HttpModules.UrlRewriteModule, DotNetNuke.HttpModules" preCondition="managedHandler" />
and under
<system.web>
<httpModules>
<add name="UrlRewrite" type="DotNetNuke.HttpModules.UrlRewriteModule, DotNetNuke.HttpModules" />
Both entries were done by the standard installer. As I am new to dotnetnuke, I don't know what either one does, so don't want to remove anything that your instructions didn't tell me to remove.
The error was:
I can't paste the error or submit button don't work. It is not pop up blocker as the first 2 pastes showed a pop up - perhaps because it is code? I emailed it to you, perhaps you can try to paste it here?
