Requiring OPCache to be disabled for WHMCS 8.12 on domains that are shared with a WordPress site creates a conflict.

[tracedef]

We are unable to disable OPCache for our WordPress website at domain.com for performance reasons, but having whmcs live at domain.com/help creates a conflict since 8.12 requires opcache to be disabled. Are there any alternatives to not upgrading to 8.12? aa

It's not required to disable opcache.. it's just a warning.. you can ignore the warning (dismiss it).

[Slaweally]

Add a .user.ini File to the /help Directory:

Create a new file in your /help folder and name it .user.ini.

Add OPCache Setting to the file:

opcache.enable=0

Apply Changes:

    Make sure that the necessary configurations for your server to read .user.ini files are enabled.
    If necessary, restart PHP-FPM or the web server:

        sudo systemctl restart php-fpm
        sudo systemctl restart apache2 # or nginx

Conclusion: These steps will allow you to keep OPCache enabled on the main area of your WordPress site by simply disabling OPCache in the /help directory. This way, you can maintain your WordPress performance while remaining compatible with WHMCS 8.12.

Is there are way to turn the warning off for disabling OPCache so I dont see the banner on the top of the page and other locations?

Hi @Chip,

The yellow warning banner at the top of the Admin Area can be dismissed by clicking the x icon in the top-right corner.
