DNN Blog Module 404 Error on Reading Post

When using DNN Blog Module you receive 404 page cannot be found error

The symptoms of this are fairly easy. When you click on the Read more link or the title of a blog that would normally take you to the full article of the blog. The page instead displays a 404 error.

 If you explore the URL you will find that the URL references the blog title something like this: http://canopi.com.au/Blog/Post/355/Single-Server-Sign-On-SSO-Part-1 

 take note that the URL does not end with the .aspx

The Cause

The URL of the blog post is being rewritten through the friendly URL settings within the later versions of DNN.

 the friendly URL settings can be found within: HOST /  ADVANCED SETTINGS / FRIENDLY URL SETTINGS

 and by default in the later versions of DNN are enabled.  The problem arises when the web.config file is missing a setting for the advanced URL rewriting.

 The Fix

 the fix is very easy and involves editing  the web.config file.

1. Take a backup of the web.config file for your site
2. Open the web.config file, and search for ‘urlformat’. You should find this in the section, like this:

<add name="DNNFriendlyUrl" type="DotNetNuke.Services.Url.FriendlyUrl.DNNFriendlyUrlProvider, DotNetNuke.HttpModules" includePageName="true" regexMatch="[^a-zA-Z0-9 _-]" urlFormat="humanfriendly" />

3. Change the urlFormat value to ‘advanced’, like this:

<add name="DNNFriendlyUrl" type="DotNetNuke.Services.Url.FriendlyUrl.DNNFriendlyUrlProvider, DotNetNuke.HttpModules" includePageName="true" regexMatch="[^a-zA-Z0-9 _-]" urlFormat="advanced" />
