Hey flipper1960,
Sorry for the late reply, and thanks for the login and test page, so I have not used the Meow Lightbox plugin before so in my research I found the plugin was giving the same error as reported here to the plugin author, the solution for this error is to remove this from the “lightbox.js” script:
//# sourceMappingURL=lightbox.js.map
This may have not been necessary, but I wanted to rule it out. Anyways, I wanted to isolate the behavior of the Meow plugin & the Magnific Popup lightbox which is the default lightbox, typically other lightbox scripts use a similar script for the lightbox. So I first tried using the “exclude” function in the Magnific Popup lightbox, which is in the file \wp-content\themes\enfold\js\avia-snippet-lightbox.js on line 211, with the lightbox option in the theme set to disabled, but with this setting the Meow Lightbox plugin fires first and loads, but then is redirected to the image file. If you watch very closely you will see that the plugin is working but I believe the Magnific Popup lightbox is embedded deeper than it seems.
So as a workaround, I enabled the Magnific Popup lightbox in the theme options and added this script in your functions.php file:

function custom_script(){
  ?>
  <script>
(function($){
  $('body').on("click", ".lightbox", function () {
	  setTimeout(function(){
	  $('button.mfp-close').trigger('click');
		  }, 200);
  });
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_script');

I also replaced your Meow Lightbox plugin “Selector” classes with “.avia-gallery a” to target this one element, I understand you want to add more, but if we can get this one element to work first then we can move forward on the other elements.
So now on your test page, the “avia-gallery” is working for the Meow Lightbox plugin, please clear your browser cache and check.

Best regards,
Mike

Hey Severin,

Thanks for contacting us and sorry for the late reply!

You can read more about cookie options here – https://kriesi.at/documentation/enfold/privacy-cookies/#default-cookie-and-services-option-settings.
You are currently using “User must accept and must opt in, only essential cookies selected” option so you can simply go to Enfold theme options > Privacy & Cookies > Cookie Handling > Buttons and add a new button below “OK, Weiter” and choose “Do not accept and hide notification” for button action :)

If you are planning to install WooCommerce, we would recommend you to use “Essential cookies are accepted on first page load, user must opt in” instead so cart would not be reset if cookies were accepted/rejected after adding items to cart.

Best regards,

Hi,

Thanks for that. Please try the following in Quick CSS under Enfold->General Styling:

@media only screen and (max-width: 1380px) {
.page-id-5571 .avia-builder-el-11 .avia-button.avia-size-medium {
    padding: 13px 20px 12px;
}
}

If you need more specific CSS then please try assigning a class to the right column in the element options.

Best regards,
Rikard

Hi,

Please change your code in Functions.php file to following one

<?php
/*
* Add your own functions here. You can also copy some of the theme functions into this file. 
* WordPress will use those functions instead of the original functions then.
*/
function enqueue_parent_theme_style() {
      wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
add_action( 'wp_enqueue_scripts', 'enqueue_parent_theme_style');

/* Proper way to enqueue styles and scripts
 */
function theme_name_scripts() {
	wp_enqueue_style( 'style-name', get_stylesheet_uri() );
}
add_action( 'wp_enqueue_scripts', 'theme_name_scripts' );

function change_cf_from() {
    return " (Email address hidden if logged out) ";
}
add_filter('avf_form_from', 'change_cf_from', 10);

/* Activate Avia debug mode */
add_action('avia_builder_mode', "builder_set_debug");
function builder_set_debug()
{
	return "debug";
}
add_filter('avf_title_args', 'avf_title_args_mod', 99, 2);
function avf_title_args_mod($args,$id)
{
     if ( $args['title'] == 'Calendar of Events' ) 
     {
        $args['title'] = 'Veranstaltungskalender';
     }
    return $args;
}
add_action('tribe_events_single_event_after_the_content', 'tribe_events_single_event_after_the_content_mod');
function tribe_events_single_event_after_the_content_mod() {
	echo "";
	echo do_shortcode("[av_social_share title='Teile diese Veranstaltung' style='' buttons='' custom_class='shareva']");
}
add_theme_support('avia_template_builder_custom_css');
add_filter( 'wc_gzd_revocation_admin_mail', 'my_child_set_revocation_admin_mail', 10, 1 );
function my_child_set_revocation_admin_mail( $mail ) {
   return  (Email address hidden if logged out) ';
}
   add_filter('avf_title_args', 'fix_single_post_title', 10, 2);
function fix_single_post_title($args,$id)
{
if (is_single)
{
$args['title'] = get_the_title($id);
$args['link'] = get_permalink($id);
$args['heading'] = 'h1';
}

return $args;
}
/* Code zum Loeschen von Veranstaltungen 
$allposts= get_posts( array('post_type'=>'tribe_events','numberposts'=>-1) );
    foreach ($allposts as $eachpost) {
      wp_delete_post( $eachpost->ID, true );
    }
	
	 $allposts= get_posts( array('post_type'=>'tribe_organizer','numberposts'=>-1) );
    foreach ($allposts as $eachpost) {
      wp_delete_post( $eachpost->ID, true );
    }
	
	 $allposts= get_posts( array('post_type'=>'tribe_venue','numberposts'=>-1) );
    foreach ($allposts as $eachpost) {
      wp_delete_post( $eachpost->ID, true );
    }    */

If that does not help, please go to Enfold theme options > Performance tab and toggle “Responsive Images” option and check if that helps.
As Nikko mentioned, certain image sizes are loading fine but certain are not loading so I believe it might be related to responsive images setting.

Best regards,
Yigit
