    I am getting the following warning when activating QM on a particular site:

    Warning: mysqli_free_result(): Couldn't fetch mysqli_result	

Count: 1

Location: wp-includes/wp-db.php:1322	mysqli_free_result()

Call Stack: get_option()
get_site_option()
maintenance_nag()
do_action('admin_notices')

Plugin: query-monitor

    I am running WP 4.1, PHP 5.5.18, MySQL 5.5.40, on Apache (version unknown).

    Does the warning still show up if you enable WP_DEBUG and then deactivate Query Monitor? If so, can you try disabling your other plugins one by one and see if another plugin is the cause?

    It looks like Query Monitor is erroneously reporting this as being caused by itself, but I don’t think this is the case.

    Let me know.

    Enabling WP_DEBUG and deactivating QM produces this message:

    Warning: mysqli_free_result(): Couldn't fetch mysqli_result in ~/wp-includes/wp-db.php on line 1322

    Thanks for trying that! It looks like the problem is being caused either by another plugin on your site or by some sort of configuration problem with MySQL.

    If you have any other plugins activated on your site, try deactivating them one by one to see if the error disappears.

    Yes, you’re right. The problem appears to be caused by Plainview Activity Monitor, which is strange because it’s working perfectly on other sites and I’m using PHP 5.5. I’ll try deleting and reinstalling.

    Thanks again.
