Have you any link for us? Is it a selfhosted Video – or a Youtube ( Vimeo etc. pp.) one?

and by the way if you have only the url of the video ( like on selfhosted one ) try it with ?iframe=true

i guess it is always the case if there are more than one parameter added ( like on most youtube videos ) the first added Parameter got the questionmark “?” and all the others come with ampersand “&“

Not for that – your welcome

well there is an if clause that could fit for your needs:
if(is_user_logged_in())
but the most elegant method would be to influence the header_searchicon from Enfold Options dialog.
This here only hides or shows the search – but better would be that there is no search in the menu
(comes to functions.php of your child theme)

function login_state(){
if(is_user_logged_in()){
?>
 <script>
	jQuery("#menu-item-search").css("display", "block");
 </script>
<?php
}
else{
?>
 <script>
	jQuery("#menu-item-search").css("display", "none");
 </script>
<?php
}
}
add_action('wp_footer', 'login_state');

maybe a filter like avf_header_setting_filter could do the needed trick – but i do not see how to ( on that early time )

this here seems to work better: https://wordpress.org/plugins/edit-author-slug/

you will have then additional fields to customise the permalink structure and the shown name – which is not the loggin User name

Edit: if you want to create it afterwards – i guess you have to refresh permalinks and edit for each user the account info !

if you like to use contact form 7 install that little honeypot plugin for CF7 too.
I got one customer who has the same troubles with spam – after installing cf7 and placing that honeypot field on his page he told me he got a lot less spam and without any captcha.

that code was to solve your problems with mega-div

Can you first test this in your quick css :

#header .avia_mega_div {
    overflow: visible !important;
}

then we will see what it is with your slider.

Darf ich gerade mal ein wenig deutsch hier einstreuen? Geht mir auch schneller von der Hand.
Wo hast du den Code eingefügt? Weil ich diesen nicht in dem quick css der angegebenen Seite finde.
Schreibst Du den Style Code in das style.css deines Child-Themes direkt hinein ?
Enfold hat hierfür ja das quick css.

maybe this could help you – i recognized it aswell on firefox and on a different alb element with tabs only:
https://kriesi.at/support/topic/tabtitles-on-the-left/

this was my proposed solution

.tab.active_tab {
    outline: none !important;
}

if you got a link for us – it will be helpfull to give you the right selector. I can not reproduce it on my installation
or try this as my next guess

.av-active-tab-title {
    outline: none !important;
}

but think of : i’m participant as you – so i can not see links in private content field.

PS : this code will work if gutenberg is deactivated by (classic plugin) otherwise we had to manage the gutenberg_plugin_active state too.

I do not need the gutenberg – so on my test installation the “classic editor” plugin is running – so the first part of the rules is not needed:
This is the part in the class-avia-gutenberg.php:

		/**
		 * Add info about ALB to post title
		 * 
		 * @since 4.5.1
		 * @param array $post_states
		 * @param WP_Post $post
		 * @return array
		 */
		public function handler_display_post_states( array $post_states, WP_Post $post )
		{
			if( $this->has_wp_block_editor )
			{
				if( $this->need_classic_editor_links() && ! $this->force_classic_editor( $post->post_type ) )
				{
					if( has_blocks( $post->ID ) )
					{
						$post_states['wp_editor'] = $this->gutenberg_plugin_active ? __( 'Gutenberg Editor', 'avia_framework' ) : __( 'Block Editor', 'avia_framework' );
					}
					else
					{
						$post_states['wp_editor'] = __( 'Classic Editor', 'avia_framework' );
					}
				}
				
				/**
				 * Remove double post status entries - have numeric keys
				 */
				if( $this->classic_editor_plugin_active || $this->gutenberg_plugin_active )
				{
					foreach($post_states as $key => $value ) 
					{
						if( is_numeric( $key ) )
						{
							unset( $post_states[ $key ] );
						}
					}
				}
			}
			else if( $this->gutenberg_plugin_active )
			{
				if( ! has_blocks( $post->ID ) )
				{
					$post_states['wp_editor'] = __( 'Classic Editor', 'avia_framework' );
				}
			}
			
			if( '' != Avia_Builder()->get_alb_builder_status( $post->ID ) )
			{
				$post_states['avia_alb'] = __( 'Advanced Layout Builder', 'avia_framework' );
			}
			
			return $post_states;
		}

with the last code i provided the list view on my test is:

maybe try this in your functions.php of your child-them

add_filter('display_post_states','remove_ALB_post_state',999,2);
function remove_ALB_post_state( $post_states, $post ) {
	if("! has_blocks( $post->ID )") {
		unset($post_states['wp_editor']);
	}
	if("!= Avia_Builder()->get_alb_builder_status($post->ID)") {
		unset($post_states['avia_alb']);
	}
return $post_states;
}

and if you want only get rid of classic :

add_filter('display_post_states','remove_CLASSIC_post_state',999,2);
function remove_CLASSIC_post_state( $post_states, $post ) {
	if("! has_blocks( $post->ID )") {
		unset($post_states['wp_editor']);
	}
return $post_states;
}
