Fatal out of memory since update! | PHP = 256m

    Ever since the latest update of wordfence all the scans that I try to do are met with a message that states “Fatal out of memory”.

    Before the update everything was fine, my PHP has always been set to 256m in the wp-config.

    I’ve posted the wordfence diagnostic below, any help on this would be massively appreciated as I currently manage 15+ websites all using wordfence.

    Wordfence Memory benchmarking utility version 6.1.7.
    This utility tests if your WordPress host respects the maximum memory configured
    in their php.ini file, or if they are using other methods to limit your access to memory.

    –Starting test–
    Current maximum memory configured in php.ini: 256M
    Current memory usage: 67.00M
    Setting max memory to 90M.
    Starting memory benchmark. Seeing an error after this line is not unusual. Read the error carefully
    to determine how much memory your host allows. We have requested 90 megabytes.
    Completing test after benchmarking up to 80.25 megabytes.
    –Test complete.–

    Congratulations, your web host allows you to use at least 80.25 megabytes of memory for each PHP process hosting your WordPress site.

  • Hello jonyfox,
    could you provide the full error message please so I can see where the error is being thrown from? (I’m suspecting wp-db.php?). If you are worried about exposing paths just blank those out and leave the filename.

    Thanks in advance!

    Hello,

    Sorry for the wait, yes it appears it is the WP-DB.PHP

    I’ve replaced my URL with ‘example’ to hide the paths.

    Fatal error: Out of memory (allocated 164626432) (tried to allocate 18203969 bytes) in /home/sites/Example.co.uk/public_html/wp-includes/wp-db.php on line 1262

    Thanks

    Hello jonyfox,
    we have a fix coming in the next release. It will not fix all instances of this problem but it should fix most of them. The mysqli plugin is required for the fix to work. You can check whether you have mysqli plugin by clicking on “Click to view your system’s configuration in a new window” at the bottom of Wordfence page “Diagnostics”.

    Hello!
    Version 6.1.8 is now available and it includes this fix: “Change wfConfig::set_ser to split large objects into multiple queries”. We are hoping that this fix will sort out most issues with the prepare function in wp-db (wp-db.php lines 1246-1266in WordPress 4.5). The fix does require the PHP extension MySQLi. You can check if MySQLi is enabled on your site via the “Click to view your system’s configuration in a new window” on Wordfence Diagnostics page. Just click that link and see if you find “MySQLi” on the list. If your host has disabled php_info, please contact your host to find out if you have the extension MySQLi.

    Please update to the latest version of Wordfence and let us know how you’re doing after that!

    Hi,

    Thanks for fixing this, i’ve been able to run scans on my websites now.

    I will change my review to reflect this.

    Thanks
