I have attached the log in details.

It happens when you edit any page. I have included a link in Private.

I removed the custom code that is in the functions file and it worked, however I don’t know what is causing the error in the code, I think it might be a missing bracket. Is there any way to check?

<?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.
*/
//set builder mode to debug
add_action('avia_builder_mode', "builder_set_debug");
function builder_set_debug()
{
  return "debug";
}
/* Change Blog Archive Style  */

function change_blog_archive_style() {	
	global $avia_config;
	if(!is_single()){ $avia_config['blog_content'] = "excerpt_read_more"; }
}
add_action('get_header', 'change_blog_archive_style');

add_filter('avf_builder_boxes', 'add_builder_to_posttype');

function avf_alb_supported_post_types_mod( array $supported_post_types )
{
  $supported_post_types[] = 'bar';
  $supported_post_types[] = 'event';
    $supported_post_types[] = 'restaurant';
	  $supported_post_types[] = 'saunas';
	    $supported_post_types[] = 'clubs';
		  $supported_post_types[] = 'shopping';
		    $supported_post_types[] = 'galleries';
  return $supported_post_types;
}
add_filter('avf_alb_supported_post_types', 'avf_alb_supported_post_types_mod', 10, 1);

add_action('wp_footer', 'add_custom_css');
function add_custom_css() { ?>
	<script>
		jQuery(document).ready(function($) {

		});
	</script>
	<style>
		@media only screen and (max-width: 767px) {
			.single-post #footer div .av_one_third {
			    margin: 0;
			    margin-bottom: 20px;
			    width: 100%;
			}
		}
	</style>
	<?php
}

when I put this code in, yes I get the error, when I take it out it works.

I tried removing that code, still get the error.. its frustrating.

Great thank you that worked perfect.
