I was just told by the author of Customer Facebook Feed that this error also exists on an other site (www.vakantiehuisverhuur.eu). The FB-plugin has not yet been installed there. So the error is certainly a CF-7 issue. But harmless also there where it concerns the contact- and booking function.
It looks like a incompatability between the two plugins. But can this be solved?
It is a marriage between CF7 and a Facebook feed. Both partners are very well but in their relation there is a weakness. Does this contribute to solve it? It is a part of the CF7f-script in scripts.js with the ajaxForm instruction:
(function($) {
if (typeof _wpcf7 == ‘undefined’ || _wpcf7 === null) {
_wpcf7 = {};
}
_wpcf7 = $.extend({
cached: 0
}, _wpcf7);
$.fn.wpcf7InitForm = function() {
this.ajaxForm({
beforeSubmit: function(arr, $form, options) {
$form.wpcf7ClearResponseOutput();
$form.find(‘[aria-invalid]’).attr(‘aria-invalid’, ‘false’);
$form.find(‘img.ajax-loader’).css({ visibility: ‘visible’ });
return true;
},
etc. etc.
In the first part a wrong sitename has been specified. However not very important I’d liked to correct this.
The sitename is http://www.vakantiehuizenwallonie.nl.
Is there anyone who can tell me in which file this ajaxForm-function is to be found. Possibly I have an incomplete CF-7 implementation.
This problem has been solved. A friend found out that I had an old jQuery-implementation (ver 1.11 and at least 1.15 was needed). On internet I found some coding (below) to do the job and load version 2.1.4. That was the beginning of the solution. After some other changes the Facebook-feed worked allright.

I have added this to a functions.php in my theme-child:
function current_jquery($version) {
global $wp_scripts;
if ( ( version_compare($version, $wp_scripts -> registered[jquery] -> ver) == 1 ) && !is_admin() ) {
wp_deregister_script(‘jquery’);
wp_register_script(‘jquery’,
‘http://ajax.googleapis.com/ajax/libs/jquery/’.$version.’/jquery.min.js’, false, $version);
}
}
add_action( ‘wp_head’, current_jquery( ‘2.1.4’ ) ); // change number to latest version
