After disabling all our plugins, we finally determined that the NextGen Gallery Plugin Version 2.1.69 was causing a PHP Warning message in the PHP log as seen below:

[25-Jan-2017 22:12:42 UTC] PHP Warning: Parameter 2 to M_DataMapper::set_custom_wp_query() expected to be a reference, value given in D:\mysite.com\wp-includes\class-wp-hook.php on line 298

If we disable the plugin the warning message in the server logs goes away.

Got the same error, tried to install an older version of NextGen but it did not help. It is when I am running a website on one.com I get the error, not with other providers.

But it is a pain in the ass since the site is based on NextGen Gallery.

@websiteworld – We will be looking at refactoring for PHP 7.1 issues although unfortunately I do not have a timeline at the moment, our apologies for these warning messages filling up the PHP error_logs although in and of themselves you should not be seeing any specific issue.

Thanks!

@nevis-1 – Thanks for your update although it would be more relevant to your own topic.

@photocrati So are you saying that the warning message isn’t really a big problem?

I added this code to the nggallery.php to suppress the warnings for now.

<?php
// Turn off all error reporting
error_reporting(0);
?>

@websiteworld – Correct, warnings are very much a nuisance and we will be working to get those cleared (at least in production environments to start with).

Thanks for sharing your work-around as well!

Just for anyone else finding this via google looking for a quick fix, add
error_reporting(1); instead of 0 at the top of the wp-content/plugins/nggallery.php file.

0 disables all error logging, including fatal errors. You want to log fatal errors, because these are the type likely to break your site!
