Also trying to implement this and quite new. Could someone tell me where to add this code?

You can add it to your functions.php or save the above code as pmp-buddyrpress.php and put it in a folder in your plugins folder. See https://www.elegantthemes.com/blog/tips-tricks/how-to-create-a-wordpress-plugin for some basic info on writing your own plugin...but this has all been done for you...you just need to install it. :-)

BTW, if you wish to add more to the plugin that block pages to non-members you can edit this section:

//lock some things for members only
$members_only = array(
"/members/",
"/activity/",
"/forums/",
"/groups/",
"/register/"
);
foreach($members_only as $check)
{
//prep for regex
$check = str_replace("/", "[/]+", $check); //replace /
$check = str_replace("/", "[^\/]/", $check); //replace * in middle of URIs
$check = str_replace("+", "+.", $check); //replace * at end of URIs
$check = "/^" . $check . "/?/"; //add start/end /

	//make sure they are a member
	if(preg_match($check, $uri) && !pmpro_hasMembershipLevel())
	{			
		wp_redirect(pmpro_url("levels"));
		exit;
	}
}	

}
add_action("init", "pmpros_hide_buddy_press_pages");

All you need to do is name it a file and upload it into the plugin folder and activate it. This is already set up as a plugin for wordpress.

Thank you for this. This was the only working snippet I could find to restrict members from accessing buddypress pages.
