 * Hi
 * I’ve installed WP Members on a development site to test it for a customer.
 * The site is built with Oxygen Builder.
 * Everytime I try to change the restriction on a post or page either from restricted
   to not restricted or vice-versa I get server 500 errors.
 * AH01071: Got error ‘PHP message: PHP Notice: ob_end_flush(): failed to send buffer
   of zlib output compression (3) in /var/www/vhosts/xxxx.xxxx.xxx/httpdocs/wp-includes/
   functions.php on line 5107 PHP message: PHP Notice: ob_end_flush():
 * It’s difficult to send you a URL because the site is password protected.
    PHP
   7.4.27 Wordpress 5.8.3
 * Any ideas?

 * Is that when you update post restriction using the bulk action in Posts > All
   Posts, or when doing it on an individual post?

 * Hi
 * It’s when we are doing it on an individual post.
 * It may be related to debug being enabled as we’ve tried turning it off and it
   seems to work more reliably.
