Yes - thanks @pamtbaau , just wanted to get the confirm on that from someone with a bit more familiarity with Grav in general.
Instagram plugin is v1.3
Facebook is v1.7
I can say that the Instagram one doesn’t work because it’s definitely using the wrong url. I think I have a hope of fixing this as it’s a case of rebuilding the string in the php.
The Facebook one - I’m not so confident about this one, the requirements for Facebook according to docs in developer pages seem to include an auth token as well as appID and an actual page ID as well and the plug-in only includes App secret and App ID so I’m guessing it’s quite a while since this has been updated.
