  • Hi, @ghrix

    Try deactivating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, try switching to the Twenty Seventeen theme to rule-out a theme-specific issue (theme functions can interfere like plugins).

    Thanks.

    Hello @wbcomdesigns

    Thanks for the reply.
    I’ve tried plugins deactivation. Revolution Slider is causing problem, but I am not getting th exact issue.
    I’ve even tried removing the functions from plugin core files.

    Thanks & Regards

    Same error on a single WP site. Disabling Revolution Slider stops error message displaying.
