Last year Twitter changed their API which caused a lot of custom blocks which implemented the Twitter API to stop working. Today I will tell you how we can re-add this feature into Moodle without any block development.
1. Open the Twitter account that you want to show in Moodle and navigate to this page: https://twitter.com/settings/widgets
2. Click “Create New” to create a new widget and copy the html code to your clipboard (Ctrl + C)
2. Turn on Editing and add a new HTML block. You can do this by turning editing on on the home page, find the “Add a Block” block, as shown below, and then select “HTML”.
