 * Hello,
 * after updating to php 7.3 i get this error message:
    Warning: Parameter 2 to 
   wp_hide_post_Public::query_posts_join() expected to be a reference, value given
   in mysite.com/wp-includes/class-wp-hook.php on line 303
 * I am using the latest version of the plugin.
    Any ideas what could be the problem?

 * Hi [@zetona](https://wordpress.org/support/users/zetona/)
 * Thank you for reporting this. I will check that error for php7.3.
 * I still haven’t pushed the latest version on the repo here, but you can find 
   it on [https://github.com/martinjankov/whp-hide-posts](https://github.com/martinjankov/whp-hide-posts)
   if you need.
 * Best,
    Martin

 * Hello Zetona,
 * I just noticed this error and actually that is not from my plugin.
    That error
   comes from a plugin called WP Hide Posts, not WordPress Hide Posts (which is 
   mine).
 * I think the plugin you use is not on the WordPress repo anymore.
