Support » Plugin: Contact Form 7 Signature Addon » [Violation] Added non-passive event / signature_pad.min.js?ver=4.2.2:1

  • Hi,

    I get the following error message relevant to the Plugin:

    [Violation] Added non-passive event listener to a scroll-blocking ‘touchstart’ event. Consider marking event handler as ‘passive’ to make the page more responsive. See

    Could this issue be related to the CF7 cf7-conditional-fields plugin, as suggested on:

    Can you please provide a solution?

    disabling the conditional field plugin on staging site, brought to error message to disappear. On Live site the error message is still there.

    I’ll email you a print screen.

    Any thoughts of a solution?
