"Your Site Doesn't Include Support for this Block" Error
If you have Stackable activated and you are encountering an error in your Block Editor that says “Your Site Doesn’t Include Support for this Block”, please try the following solutions:
Clear your browser’s cache
Try clearing the cached files from your browser privacy settings. Do a hard refresh on your browser by holding the shift key while reloading the page (SHIFT + F5 for Windows or SHIFT + ⌘ + R for Macs)
This usually is a browser caching issue, and doing the above should force your browser to load the latest Stackable plugin files.
Make sure you’re using the latest version of Stackable
WordPress updates can include changes to the Block Editor. To make sure things work smoothly, you will need to update to the latest version of Stackable: https://wordpress.org/plugins/stackable-ultimate-gutenberg-blocks/
