Error Message: Edit Entries Form

On the page with edit entries. I tried to edit and save as “submitted” and I get an “Unexpected Error” popup.

I get the following error: “Uncaught Error: Call to undefined method rednaoeasycalculationforms\ajax\EntriesAjax::UpdateField() in /home/hostafam/public_html/wp-content/plugins/all-in-one-forms/ajax/AjaxBase.php:63 Stack trace: #0 /home/hostafam/public_html/wp-includes/class-wp-hook.php(308): rednaoeasycalculationforms\ajax\AjaxBase->rednaoeasycalculationforms\ajax\{closure}() #1 /home/hostafam/public_html/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #2 /home/hostafam/public_html/wp-includes/plugin.php(517): WP_Hook->do_action() #3 /home/hostafam/public_html/wp-admin/admin-ajax.php(188): do_action() #4 {main} thrown – #0 /home/hostafam/public_html/wp-includes/class-wp-hook.php(308): rednaoeasycalculationforms\ajax\AjaxBase->rednaoeasycalculationforms\ajax\{closure}() #1 /home/hostafam/public_html/wp-includes/plugin.php(205): WP_Hook->apply_filters() #2 /home/hostafam/public_html/wp-includes/functions.php(3661): apply_filters() #3 /home/hostafam/public_html/wp-includes/class-wp-fatal-error-handler.php(239): wp_die() #4 /home/hostafam/public_html/wp-includes/class-wp-fatal-error-handler.php(154): WP_Fatal_Error_Handler->display_default_error_template() #5 /home/hostafam/public_html/wp-includes/class-wp-fatal-error-handler.php(58): WP_Fatal_Error_Handler->display_error_template() #6 [internal function]: WP_Fatal_Error_Handler->handle() #7 {main}”
