Email log on PHP 8 causes PHP Fatal memory error

  • I have recently upgraded my site to PHP 8.0.26 and now when I go to the Email log page I get an error “There has been a critical error on this website.”.

    The error log has this corresponding error:

    [06-Dec-2022...] PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 81920 bytes) in /xxxx/public_html/staging/wp-includes/class-wp-object-cache.php on line 319

    PHP mem limit is set to 512M, the max on my hosting. If I switch back to PHP 7.4, I get no errors and can view the email log without issue.

    The email log contains 3,583 items.

    Any help greatly appreciated.

    Colin

    Just deleted all email logs directly from database (on staging system) and I can now view the email log on PHP 8, so definitely related to number of logs in db. -C

    @colinfroggatt Hi,

    I hope you are doing well.

    I think this is happening because of PHP memory settings.

    Fixing Error: There are a couple of ways to resolve this error. These include:

    1. Editing the wp-config.php file
    2. Editing the php.ini file
    3. Editing the .htaccess file

    1. Editing the wp-config.php file

    Here you will need to edit the wp-config.php file.
    define( ‘WP_MEMORY_LIMIT,’ ‘1024M’ );

    2. Editing the php.ini file

    On a live install, the file can be accessed within the root of your install, within the /public_html/ folder. Note that WordPress does not install the file but, in most cases, is set up by your host. For example, if you are using CPanel as your control panel, ensure the checkbox for “Show Hidden Files” is checked and then click Go. You may check into this article on how to edit the file. Before editing the file, kindly take a backup of it by downloading it to your computer.
    Once this is done, open the file, and add or edit the following line:

    memory_limit 512M

    3. Editing the .htaccess file

    The .htaccess file is a file located within the root of your WordPress files.

    You will need to add or edit the following code to the bottom of the file:

    php_value memory_limit 256M

    With this done, you can then save your changes and check if the error is resolved.

    You can read more about this here.

    Before doing anything, create a backup of your file or website.

    Thanks
