TypeError: xhr.responseJSON is null

  • Hello,
    I use WordPress, CF7 and Conditional Fields for Contact Form 7 in the latest version. Unfortunately, when I submit my form, I sometimes get the error message in the JavaScript console:

    
TypeError: xhr.responseJSON is null  scripts.js:241:13

    My Testpage

    What can be the reason? Many thanks for your help!

    it’s a big form, so it might be due to too much data getting submitter trough the post request. Could by a setting in your PHP.ini config. In order to know for sure, could you create a smaller form and see if the error also occurs on that one?

    Thank you for your quick response.
    The problem is, the error only occurs occasionally.
    The e-mail will be sent anyway, but no success message will be displayed and the small arrows will rotate without end.
