Sitecore 8 dialogs not working?

Recently I’ve seen Sitecore fail to load the JavaScript files for Speak and so break using the Sitecore desktop by failing to load dialogs in the content editor and in the control panel. This can happen in a couple of ways and the reasons behind it are pretty subtle. The issue I found for this post was that the SPEAK javascript files were not loading.

The SPEAK system relies on a set of config files in the App_Config/Include folder and client libraries inside the sitecore/shell folder. To ensure that the configuration is loaded correctly and the JavaScript files are returned, you need to check:

  1. ‘/App_Config/Include/.Sitecore.Speak.Important.Config’ – make sure this doesn’t have the hidden attribute set. If you need to, remove the ‘.’ prefix to force a refresh
  2. Double check that all the client assets also don’t have the hidden attribute set.

To test that everything is ok, visit the following URL: <Your_Host>/-/speak/v1/assets/main-1.2.js

You should see the require.js calls setup and loading the libraries necessary for the Sitecore desktop. In another post I’ll cover how you can turn on minification and etags!

Hope this saves you some time!
