# Problem with ot-loader.php

 * As of today my website ([http://www.skmbrussels.be](http://www.skmbrussels.be))
   started giving me an error messages:
 * Notice: Only variables should be passed by reference in skmbrussels.be/web/wp-
   content/themes/hueman/option-tree/ot-loader.php on line 98
 * Notice: Only variables should be passed by reference in skmbrussels.be/web/wp-
   content/themes/hueman/option-tree/ot-loader.php on line 326
 * I tried to google this issue but I have not managed to find a solution to this.
   I am using a child theme which I created myself (so not through the Childify 
   plugin). I found on the net that this is a message produced by PHP. I tried to
   turn off displaying error messages (i.e. changing ‘display_errors’ to off).
 * Since this error message is very annoying, I would appreciate any help on this!

 * MY ISP recommended to downgrade PHP to 5.6. I was using PHP 7 version. It thus
   seems that Hueman is not compatible with the PHP 7.

 * [@vsolanic](https://wordpress.org/support/users/vsolanic/) – I have two sites
   running Hueman v3.1.6 on PHP v7 without any problems.

 * Hi bdbrown,
 * I can reactivate the PHP v7 if you would like to look at it. But as I explained
   above, downgrade of the PHP to v5 removed the error messages.
 * Do you want to look at it? Shall I reactivate the PHP v7?

 * You don’t need to change it. Although it doesn’t affect the functionality of 
   the theme it’s been identified as a bug as noted here:
    [https://github.com/presscustomizr/hueman/issues/241](https://github.com/presscustomizr/hueman/issues/241)
 * PHP “display_error” is not normally active on a production site:
    [http://php.net/manual/en/errorfunc.configuration.php#ini.display-errors](http://php.net/manual/en/errorfunc.configuration.php#ini.display-errors)
 * In my experience it is normally disabled by the host default PHP configuration.
   If you’ve tried to disable it and you still see the notices then there is something
   else in the PHP configuration, or possibly your .htaccess file, that’s keeping
   that from working.
 * You can check your host PHP configuration using a phpinfo file:
    [http://www.inmotionhosting.com/support/website/php/create-phpinfo-page-to-see-php-settings](http://www.inmotionhosting.com/support/website/php/create-phpinfo-page-to-see-php-settings)
 * Look in the Core section for the “display_errors” and “error_reporting” options.

 * OK. Thank you for explanation. If I have time, I will play a bit with it.
 * Cheers!

 * I was also seeing these PHP Notices using PHP 7.0.6, WordPress 4.6.1, and Hueman
   theme 3.2.3. I just upgraded to Hueman 3.2.8 and the problem was solved. My thanks!
 * Philosophically, I have to say that configuring PHP to suppress error display
   might serve as a temporary work-around of last resort but is not a credible fix
   for anything. Whether during production or in a live site, I want to know when
   any of the software components is misbehaving or failing to play nicely with 
   the others. Even if I suppress error messages from public view, I need to know.
 * Warmly,
    Paul
