Unable to change membership
After upgrading from 5.36.1 to 5.37.0 I am unable to save a changed membership. When I press Save the update is not carried out and the logo keeps spinning indicating it is still busy.
Drupal Watchdog displays:
TypeError: Return value of CRM_Financial_BAO_Order::getFinancialTypeID() must be of the type int, null returned in CRM_Financial_BAO_Order->getFinancialTypeID() (regel 286 van /home/xxx/domains/xxx/public_html/sites/all/modules/civicrm/CRM/Financial/BAO/Order.php).
Notice: Undefined index: financial_type_id in CRM_Member_Form->setPriceSetParameters() (regel 488 van /home/xxx/domains/xxx/public_html/sites/all/modules/civicrm/CRM/Member/Form.php).
Please help.
