I’m trying to include ACF Pro into a plugin but it conflicts with sites that already use ACF (Regular). Specifically, Pro features such as Option pages disappear. Is there a way around this? It’d be great if there was a way to silo the two ACF instances.
The problem here is that the free version of ACF that’s installed is probably running before your version.
Also, you can’t run both ACF4 and ACF5 at the same time on the same site. The users of your plugin will need to upgrade to ACF5.
