# Plugin throws JSON error

 * Initially the popup would not display and caused scrolling issues. We solved 
   that with a bit of CSS. Now, we are encountering this error:
 * `Error: type of parsererror with message of SyntaxError: Unexpected token < in
   JSON at position 0 - site.min.js?defer&ver=1.16.1`
 * Since this file is minified it’s hard to tell what it’s doing, but it seems we
   are maybe getting HTML back rather than valid JSON.
 * This happens when the form is submitted.

 * Hello [@spiderwisp](https://wordpress.org/support/users/spiderwisp/) – we’re 
   sorry to hear that you are having this error.
 * I would suggest see if this guide gives you anything useful to go on: [Checking JavaScript Errors](https://docs.wppopupmaker.com/article/373-checking-javascript-errors)
   ​
   On a side note, you can also **Test if a Plugin or Theme Interferes with Popup
   Maker:** [https://docs.wppopupmaker.com/article/332-test-whether-a-plugin-or-theme-interferes-with-popup-maker](https://docs.wppopupmaker.com/article/332-test-whether-a-plugin-or-theme-interferes-with-popup-maker)
   This article will help you determine if its a conflict with another plugin or
   theme quickly.
 * Hope that helps.
 * If that works for you then we would very much appreciate it if you could quickly
   [rate the plugin](https://wordpress.org/support/plugin/popup-maker/reviews/?rate=5#rate-response),
   just to help us spread the word.
 * Otherwise, you can reach us directly to our HelpScout support desk. Check this
