 * Hi!
    I have a problem on my website with Contact Form 7. After pressing ‘submit’
   it causes infinite spinning wheel rotation and doesn’t show success message. 
   However email is successfully sent.
 * I get error in console:
 *     ```
       {code: "invalid_json", message: "The response is not a valid JSON response."}
       code: "invalid_json"
       message: "The response is not a valid JSON response."
       ```
   
 * Error is thrown in:
    [https://artbud.kyiv.ua/wp-content/plugins/contact-form-7/includes/js/index.js](https://artbud.kyiv.ua/wp-content/plugins/contact-form-7/includes/js/index.js)
   On line: 312
 * Wordpress ver. 5.7.2
 * Installed and activated plugins:
    Contact Form 7 Advanced Custom Fields 5.9.4
   Photo Gallery 1.5.68 Redirection 5.1.1 Webcraftic Cyr to Lat reloaded 1.2.0 WP
   Google Maps 8.1.9
 * Steps I made to solve the issue:
    - I tried to deactivate all plugins it didn’t help
    - I tried to update permalinks in **Settings->Permalinks**
    - I tried to create another contact form
    - Everything works just fine on my demo webpage – [https://artbud.neon-studio.site/](https://artbud.neon-studio.site/)
 * Reproduction steps:
    1. Go to home page 2. Click on big yellow button with label‘
   Обратный звонок’ 3. Try to send message
 * I have the same problem with another form on this page – [https://artbud.kyiv.ua/kontakty/](https://artbud.kyiv.ua/kontakty/)
   (
   When WP Google Maps activated it throws an error but if I deactivate this plugin
   I see error from Contact Form 7).
 * Thanks for your help in advance!

 * I was able to solve the problem with help of my hosting provider. Hope this will
   be useful if you also encounter this problem:
    You need to disable **display_errors**
   in PHP settings of your hosting.
