Getting this message displaying on my home page. ?? "Error validating access token: Session has expired on Sunday, 10-May-20 10:41:42 PDT. The current time is Friday, 15-May-20 10:08:38 PDT." Any ideas?
Solved! Go to the solution
Under your Apps section, select the Instafeed app. On that page there is a button to "update app" (at least there was on two of my sites that were having this problem). That alone didn't work for me, so I clicked the "Connect an Instagram Account" button to link it to the associated instagram account again, and it worked.
