    I use BPS on all of my WP websites and can usually sort out any issues by looking in these forums. However, this one has me stumped.

    I noticed today that ALL of my websites have started having a red section on the Wizard screen. It says:

    Error: Your PHP Configuration Memory Limit is set to: 32M. WordPress needs a bare minimum Memory Limit setting of 64M to perform well. Contact your Web Host and ask them to increase your memory limit to the maximum memory limit setting allowed by your Host.

    However, if I go into MultiPHP INI Editor (in cPanel), I can see that “memory_limit” is set to “768M” for each of the sites.

    Clicking on “System Info” within BPS tell ms this …

    “WordPress Admin Memory Limit” is set to 768M, but “PHP Actual Configuration Memory Limit” is set too low, at just 32M.
    What is which “PHP Actual Configuration Memory Limit” and where can I change it?

    If you are sure that your PHP memory limit is 768M then you can ignore the BPS check on the System Info page and the warning about your PHP memory limit on the Setup Wizard page.  BPS makes every possible attempt to get the PHP memory limit from a host server, but some host servers do not return a correct value for the PHP memory limit variable.


    It certainly says that “memory_limit” is set to “768M” in MultiPHP INI Editor (in cPanel), but maybe there’s an issue?

    How do I know if cPanel or BPS is correct?

    Maybe BPS is picking up on a problem?

    You can either check with your web host to make sure the PHP memory limit is really 768M or you can create a php file and add this one line of code in it below, upload the php file you created to your hosting account root folder and then use your Browser to go to view your website/server phpinfo.  Example: phpinfo — Outputs information about PHP’s configuration.  You will see to table columns under the Core section > Local Value and Master Value.  The Local Value is what your PHP config is for your website.  The Master Value is what your PHP config is for your server.  Usually you will see the same value for memory_limit for both the Local Value and Master Value table column rows.

    <?php phpinfo(); ?>

    Thanks for that.

    It looks like “memory_limit” is 768M for the Local Value and 32M for the Master Value.

    Should I worry about that Master Value?


    AITpro Admin

    That’s fine then.  The Master Value is set in your server’s php.ini file and is the PHP memory limit of 32M BEFORE any of your website’s php code is executed.  The Local Value overrides the Master Value.  So that means you have 768M of PHP memory available for executing php code.

    What used to happen pretty much all the time in previous versions of PHP was that when you changed the Local Value then the Master Value would be changed as well to whatever the Local Value is set to.  That no longer seems to happen as often in PHP7.x.  Not really sure why that is, but must be some new PHP server config thing in PHP7.x.


    Perfect. Thank you.
