    Hi!

    We are migrating our site from PHP 7 to PHP 8.

    Contact Form 7 is working well in PHP 7, but not in PHP 8.

    The working site is:
    https://www.tabiquepluvial.es/ca/contacte/
    The new site is working under this IP: 18.198.155.123
    So to test, you need to add this lines to your hosts file.
    18.198.155.123 https://www.tabiquepluvial.es
    18.198.155.123 tabiquepluvial.es

    After submitting the form, you will get the typical WordPress error page.
    and in logs:
    [14-Sep-2022 05:35:07 UTC] PHP Fatal error: Uncaught Error: Call to a member function get_result() on null in /DOCUMENT_ROOT/wp-content/plugins/contact-form-7/includes/contact-form.php:1054

    PHP 7.2.34
    Details new site:

    Solved: just increase php memory limit from 128MB to 512MB.

    I also have the same problem

    File: wp-content/plugins/contact-form-7/includes/contact-form.php
1054: 		$result += $submission->get_result();

    I try print_r line 1504 it goes through 2 times, the first time it works properly, the second time the error appears.
    A temporary fix, I don’t know the exact fix yet, but you have to fix the plugin.
    Add this line of code:

    global $wpcf7_control_init_inited;
if ($wpcf7_control_init_inited) {
 return;
}
$wpcf7_control_init_inited=1;

    In the function wpcf7_control_init at the file wp-content/plugins/contact-form-7/includes/controller.php

    The completed code will look like below, the error will be fixed:

    File: wp-content/plugins/contact-form-7/includes/controller.php
13: /**
14:  * Handles a submission in non-Ajax mode.
15:  */
16: function wpcf7_control_init() {
17: 	global $wpcf7_control_init_inited;
18: 	if ($wpcf7_control_init_inited) {
19: 	return;
20: 	}
21: 	$wpcf7_control_init_inited=1;
22: 
23: 	if ( WPCF7_Submission::is_restful() ) {
24: 		return;
25: 	}
26: 
27: 	if ( isset( $_POST['_wpcf7'] ) ) {
28: 		$contact_form = wpcf7_contact_form( (int) $_POST['_wpcf7'] );
29: 
30: 		if ( $contact_form ) {
31: 			$contact_form->submit();
32: 		}
33: 	}
34: }
