So we are using Drupal 7 and civiCRM 5.10. We want to use this extension https://github.com/civicrm/org.civicrm.contactlayout
We have installed angular profiles (4.7.31-1.1.2) and API v4 (4.3.0) as well as the contact layout (1.3.1). We also have shoreditch.
When we navigate to Administer -> Customize Data and Screens -> Contact Summary Layouts all we get is an empty civicrm screen. When we try to view a profile with these enabled we get the error 'Api ContactLayout get version 4 does not exist.'
Any ideas about this one? I have tried having a search on here and a google of this error message, but so far I haven't seen this issue?
