    Hi!

    First, thank you for this great plugin!

    There is some PHP warnings when visiting “Cached files” tab (/wp-admin/admin.php?page=flush-opcache&tab=cached_files):

    2024/06/30 14:57:51 [error] 435052#435052: *105144 FastCGI sent in stderr: "/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key "timestamp" in /var/www/EXAMPLE.COM/public_html/wp-content/plugins/flush-opcache/admin/class-flush-opcache-cached-files-list.php on line 116; PHP message: PHP Warning:  Undefined array key

    As you can see there is a lot of same warning in a one “line”. I get several lines these when I refresh page once.

    Kindly,
    Juuso

    Hi, I suspect it’s some PHP tuning.

    Are you using a shared host or your own server ?

    What version of PHP are you running and what’s the configuration of OPcache ?

    Hi!

    This is my own server.

    This happens on PHP 8.0 and 8.3.

    Hi,

    I’m sorry but I can’t find something in your configuration explaining this…

    What PHP flavour are you using ? How did you install it ?

    Hi

    This is php-fpm, installing just basic sudo apt install php8.3-fpm. And then some configurations to the php.ini file, like memory limit etc.

    Can you paste the result of a php -v ?

    Okay, it is the opcache.validate_timestamps on php.ini.

    If it is set to 0, there is no “timestamp” key. After I set it to 1, now I see “timestamp” when calling opcache_get_status()

    But I prefer to keep it set to 0.

    Ok, thank you for this information.

    This is weird cause I can’t reproduce this behaviour but I’ll filter this warning in the next release.

    And you’re right, in production environment opcache.validate_timestamps should be disable.

    Weird indeed… I just changed the value of opcache.validate_timestamps to 1, and of course restarted php process.

    But any way thank you and keep up the good work! 🙂
