In PHPfox V4, we don’t see the tag cloud in the blog section. This tutorial shows how to add that back.
Go to AdminCP >> Blocks and click Add Block on the top right.
Title: You can leave this blank as it’s a coded block so it will make its own title or you can add a title
Type: PHP block file
Component: tag >> cloud
Placement: Block 1
Submit and clear cache.
If you want it to show on all of the pages within the blog section, you would change the controller to Blog and that would make it show in the blog.index, and blog.view pages.
