1.8 Upgrade - No Charts showing in the Reports

After I upgraded to 1.8 from 1.7.x the pdf/html reports are all showing an “invalid API Module and/or API Action” message where the graphs and charts should be. The charts and graphs in the dashboard show up fine. Is anyone else encountering this? Got a solution?

Thanks for the report, bug created in: Email reports regression: graphs not displaying · Issue #3170 · matomo-org/matomo · GitHub

I’ll fix it in the next 2 days and we will release 1.8.1 to clear a few bugs

Thanks Matt, appreciate the quick response.
