Just an update to my other post. It seems the only way I found the Shortcode generator to work, meaning after selecting any shortcode the code actually being applied rather than resetting the generator modal was on an older version of wordpress.
Version 4.05 to be exact. Any combination of plugins installed, enabled, disabled, shared and private hosting would not work on 4.22 with latest framework plugin.
The working installation is without the framework plugin being installed. I’d test installing it, but I fear I’ll have to use this to build a new site and don’t want to break the only one working.
