Allow admins, administrator, administrators access to all restricted posts in WordPress with Paid Memberships Pro

pmpro_allow_access_for_admins.php

<?php
/** 
 * This code snippet allows admins without any PMPro membership level to access any restricted content.
 * Add this code to your PMPro Customizations plugin - https://www.paidmembershipspro.com/create-a-plugin-for-pmpro-customizations/
 */
 
 function pmmpro_allow_access_for_admins($hasaccess, $mypost, $myuser, $post_membership_levels){
  
  //If user is an admin allow access.
	if( current_user_can( 'manage_options' ) ){
		$hasaccess = true;
	}
	
	return $hasaccess;
}
add_filter('pmpro_has_membership_access_filter', 'pmmpro_allow_access_for_admins', 30, 4);

I have tried the suggested code via the Paid Membership Pro plugin. As a result, I could not log into my site. I got the following message"

"Parse error: syntax error, unexpected '<', expecting end of file in /home/customer/www/imalipro.com/public_html/wp-content/plugins/pmpro-customizations/pmpro-customizations.php on line 12
There has been a critical error on your website. Please check your site admin email inbox for instructions."

After I removed the snippet I could log into the site again.
Is there somebody with advice to rectify this problem?

@Pietjo please don’t copy the opening PHP tag on line 1

Thanks, Andrew

You're welcome :)
