    Hello @ronakganatra

    Hope you are doing well today.

    This is a warning and not a fatal error; it typically indicates that OPcache Save Comments is not enabled on your hosting.

    Since this setting is necessary for Defender to function correctly, you need to either contact your hosting provider or add the following code to your user.ini file to enable it.

    Please refer to this document to learn more:

    https://docs.moodle.org/500/en/OPcache

    Kind Regards
    Amin

    I hope the hosting support will be able to help you with this, however, can you please also share the Fatal error that you observed so that we can take another look at this issue?

    Looking forward to hearing back from you.

    Hello @ronakganatra

    Hope you’re doing well!

    I reviewed the fatal error and the warning, as you mentioned in the screenshot as well as the topic description, we’ve had some past reports about the issue, and as mentioned by Amin here https://ww.wp.xz.cn/support/topic/fatal-error-logged-from-the-defender-security-plugin/#post-18472566 once opcache.save_comments is enabled on your server, the Error/warning should no longer be logged.

    We have enabled the save comments, will check

    Can you please confirm if you have already enabled opcache.save_comments on the server, and you are still facing the same issue? If so, could you please try reinstalling the plugin and check if that helps?

    Please let us know how it goes.

    Kind Regards,
    Saurabh
