    I can’t access to back-end of website too.
    I have put codes into wp-config.php to hide all warning,notice etc but the error still show
    The only option is rename the wordfence folder to access the site again

    Could you please tell me about this error?

    Thanks

    Hey @whateverfree2,

    I’m sorry to hear you’re having this trouble.

    Can you send me a Diagnostics report so I can get a better overview of your environment? Please navigate to Wordfence > Tools > Diagnostics. Here you can select SEND REPORT BY EMAIL. Please include your WordPress.org username and update this thread after you’ve sent it in case the email is missed.

    Thanks,

    Gerroald
