Depending on how you’ve configured, before you uninstall SpeedBlog from the Module Definitions section of the host, ensure that the following steps are taken. Failure to do so may result in a broken DNN Installation.
Visit the Portal Settings
Remove Checkboxes for Pingbacks (Send as well as Receive)
Save the settings. Depending on your other SpeedBlog settings, you may have to revisit this page.
Remove Provider Settings
Remove (Disable) the RSS and Sitemap Providers. When you’re correctly done, you should see the Provider Settings as above.
Uninstall the module.
Always make a copy of your web.config file before you install/uninstall a product. If you have performed the above procedures correctly, you can now go to the Module Definitions page and remove all SpeedBlog modules just like another or DNN Module.
