 * Hello,
 * Great plugin but I’m having a problem. I’m getting the error message below after
   installation. Any ideas what I can do?
 *  call_user_func_array() [function.call-user-func-array]: First argument is expected
   to be a valid callback, ‘simpay_admin_php_notice’ was given in /home/—/wp-includes/
   class-wp-hook.php on line 286
 * Thanks!

 * [@saleshigher](https://wordpress.org/support/users/saleshigher/) I believe that’s
   because you’re not running PHP 5.3 or higher.
 * Please see [https://docs.wpsimplepay.com/articles/system-requirements-wp-simple-pay-pro/](https://docs.wpsimplepay.com/articles/system-requirements-wp-simple-pay-pro/)
 * However, a message telling you this should’ve come up instead of that error. 
   We’ll get that fixed in the next update.
 * Thanks,
    Phil

 * Hi Phil
 * Thanks for the reply. I got it to work by upgrading to PHP7.2.
 * It’s a bit odd because the default was supposed to be 7.0. but it didn’t work
   then. Anyway, all good now.
 * Cheers
