Everything was working fine for weeks (civicrm on drupal) then this error on the civicontribute form web page:
Fatal error: Call to undefined method CRM_Core_Payment_Manual::setBackOffice() in /var/www/html/missional/donations/sites/all/modules/civicrm/CRM/Core/Payment/Form.php on line 67
And these errors on the log in page:
Notice: Undefined index: user_name in CRM_Core_Payment_AuthorizeNet->__construct() (line 56 of /var/www/html/missional/donations/sites/all/modules/civicrm/CRM/Core/Payment/AuthorizeNet.php).
Notice: Undefined index: password in CRM_Core_Payment_AuthorizeNet->__construct() (line 57 of /var/www/html/missional/donations/sites/all/modules/civicrm/CRM/Core/Payment/AuthorizeNet.php).
Any ideas on how to resolve this?
