Just upgraded to CiviCRM 5.65.1 and now when I open contacts who I know have contributions, the tab shows the number of contributions, but the box below the tab that should list the contributions is blank and I get an error: "Unable to reach the server. Please refresh this page in your browser and try again."
The contributions show up in the Activities tab instead.
Anyone else having this problem?
Also I dug around in my PHP error log and found these two critical errors:
PHP Fatal error: Uncaught Error: Class 'Civi\Api4\PaymentProcessor' not found in /home/footprk1/public_html/wp-content/plugins/civicrm/civicrm/CRM/Admin/Page/PaymentProcessor.php:65
PHP Fatal error: Uncaught Error: Class 'Civi\Api4\ContributionPage' not found in /home/footprk1/public_html/wp-content/plugins/civicrm/civicrm/CRM/Utils/System/WordPress.php:1579
