Upgrading to 3.4 fails
I'm running Civi 5.26.2 and have tried upgrading GiftAid to 3.4. It appears to upgrade correctly, including running db updates with no logged errors, but deletes the previously existing reports (they can be rebuilt).
Secondly, the configuration screen is missing:
Error log says: Notice: Undefined variable: elementGroups in CRM_Civigiftaid_Form_Settings->buildQuickForm() (line 98 of .............../sites/default/files/civicrm/ext/uk.co.compucorp.civicrm.giftaid-3.0alpha3/CRM/Civigiftaid/Form/Settings.php).
