    Hello guys,

    A weird error happened to me today.
    I’m trying to fix it, but im still investigating the cause.
    Just sending this FYI.

    Disabling Wordfence removes the error.
    Environment:
    Linux (ubuntu)
    PHP 7.4.12
    MySQL 5.7
    WP 5.5.3

    Here’s some log lines:

    UPDATE:
    – Used Wordfence Assistant plugin to delete all WF tables and reactivated the WF plugin after without issues.
    – Seems it was some configuration in one of the tables.

    Hi @sp1ke77,

    Thanks for reporting this issue and the steps you have taken to resolve it in case other users experience the same situation. It is not clear whether the recent WordPress 5.5.3 Alpha update, or the installation of another plugin may have caused this to occur based on the info provided, but I’m really pleased to see that the Wordfence assistant was able to help resolve it. Here’s some more info you might find interesting:
