iFinity

Take a look at your web.config file.  Find the section where it says '<friendlyUrl defaultProvider="iFinity.UrlMaster">'

Then, in the line below, you'll find this entry:

<add name="iFinity.UrlMaster" type="....

In this line, search for this attribute: "pageExtensionUsage" and make sure the value is set to 'AlwaysUse'.  If it says anything else, change it to 'AlwaysUse'.

Then, look for the attribute that says 'pageExtension'.  Make sure it has a value of '.aspx'.

Then, save your web.config, and try your site again.

That problem is a 500 server error.

Note that the Url Master module is rewriting the Url OK, I can see that it outputs this Url :

http://itpcomm.com/Default.aspx?TabId=67&ALL=Edit&mid=619&ElementId=0&eType=ALL&LCTag=ALL&LCPage=ALL&ctl=Edit&mid=619&ElementId=0&eType=ALL&LCTag=ALL&LCPage

Which, if you request it, also throws the 500 server error.    This is most likely an unhandled exception on the server somewhere, possibly within the live content module.

You will have to look into your windows event log to see if you can find what the 500 server error is.  My guess is that it's the duplication of the elements of the query string : you can see in the above url that "ctl=Edit&mid=619&ElementId=0&eType=ALL&LCTag=ALL&LCPage" is repeated twice (and you can also see this in the supplied url).

You can try excluding that page by adding it to the list of pages that don't have a friendly url generated, and see if that helps.  But the main thing to find out is what is causing that 500 error.
