[Hummingbird] Performance Test Error

When I attempt to run a performance test, I get this error: The performance test didn't return any results. This probably means you're on a local website (which we can't scan) or something went wrong trying to access WPMU DEV. Try again and if this error continues to appear please open a ticket with our support heroes

I have attempted this on different networks, different (physical) locations, different days and continue to receive this msg. Any insight would be helpful, thanks!

    Hi Jason

    Hope you're having a wonderful day!

    In order to better help you with your issue, I would like to have a closer look at your site setup and settings. Could you please grant us temporary support access to your website? You can grant us access via WPMUDEV Dashboard plugin, there's no need to share credentials. Here's our detailed documentation page about it:

    Don't forget to let us know here once you'll grant it.

    Kind regards,

    Hi Jason

    Hope you're doing well!

    I've had a closer look at your site and noticed that you max_execution_time is 30 seconds, it's a bit low value and on some installation, this may cause this kind of issues with the Performance test.

    Could you try to increase it to 60-100 seconds? Here you can find detailed instructions on how to do this:

    You can check your current max_execution_time limit at the WPMU DEV -> Support -> System Info page, at the PHP tab.

    If nothing from described in the above article works for you, try to contact your hosting provider and ask if it's possible to increase max_execution_time limit for your site.

    If increasing PHP memory limit doesn't help, in order to further diagnose your issue, I'd request you to perform the two tests mentioned in the following:

    1. Could you please run a plugin conflict test to eliminate the possibility of a conflict with another plugin?

    Whenever you perform a plugin conflict test, it's always better to do so on a staging site. You can learn how to create a staging site here:

    The simplest way to perform a plugin conflict test:
    * Login to your site via FTP
    * Navigate to wp-content
    * Rename the plugins folder to _plugins
    * Create a new plugins folder
    * Move the plugin folder (ex: wp-hummingbird) you want to test from _plugins to plugins
    * Check if the issue still persists
    * Then, one at a time, move other plugin folders over from _plugins to plugins until the symptom returns

    NOTE: While you are doing this, do not visit WP Admin -> Plugins on your site. This will ensure that your plugins remain active when you copy them back over.

    2. If that does not lead to a solution, could you please enable WP_DEBUG and provide us with the output of your debug.log file?

    To enable WP_DEBUG, change the following line in your wp-config.php file:

    define('WP_DEBUG', false);

    To this:

    // Enable WP_DEBUG mode
    define( 'WP_DEBUG', true );
    // Enable Debug logging to the /wp-content/debug.log file
    define( 'WP_DEBUG_LOG', true );
    // Disable display of errors and warnings
    define( 'WP_DEBUG_DISPLAY', false );
    @ini_set( 'display_errors', 0 );

    After this, try to run another Performance test and when you'll get the error again, go to wp-content/ on your server via FTP and download the debug.log file to your local computer. Then, open that file with a text editor like notepad (Windows), GEdit (Linux), or TextEdit (Mac). You can then save the file as a .txt file and upload it here as an attachment to your post.

    We look forward to seeing the results of your tests.

    Kind regards,

    Hi Jason

    I'm glad to know that your issue is solved now.

    I would recommend you to have a look at the detailed Hummingbird documentation here:

    Also, in order to better optimize your site, I would recommend you to try Smush Pro plugin, it's a great image optimization tool which can make your site even faster:

    In addition to this, you can use the following plugins to find out slow plugin and queries on your site:
    1. Query Monitor
    2. P3 (Plugin Performance Profiler)

    And the last thing, I've noticed that you're using PHP 5.6 on your site, which is absolutely fine, but from my own experience I know that you can find better performance results if you'll upgrade your PHP version to 7.x

    Hope this will help you :slight_smile:

    Kind regards,

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
