Support » Plugin: Contact Form 7 - Conditional Fields » Conditional Fields Not Working as of Version 1.7.x

  • Resolved Urielts



    We’ve reverted our website to using CF7 CF 1.6.5 as it was the last version of the plugin that worked on our development and production environments. When updating the plugin to any of the 1.7.x versions we see the following errors:

    In Google Chrome:

    Uncaught TypeError: Cannot read property 'length' of undefined
        at scripts_es6.js:709
        at (<anonymous>)

    In Firefox:

    711            return item;

    I can send you a link to our development site if that’d help, but for the most part everything has been working as intended up until that release. I looked through the support forums, but I didn’t see any specific reference to this error type. Any help would be appreciated.
