 * Hi there, I’m getting this console error message when I’m trying to delete any
   field in the form builder. Could you take a look?
 *     ```
       wpuf-form-builder-components.js?ver=3.5.28:120 Uncaught TypeError: Class constructor rn cannot be invoked without 'new'
           at a.delete_field (wpuf-form-builder-components.js?ver=3.5.28:120:13)
           at a.n [as delete_field] (vue.min.js?ver=3.5.28:6:835)
           at click (eval at mi (vue.min.js?ver=3.5.28:7:23047), <anonymous>:8:1416)
           at HTMLElement.t (vue.min.js?ver=3.5.28:6:5467)
       ```

 * Hi [@pvnanini](https://wordpress.org/support/users/pvnanini/),
 * I’m unable to reproduce the issue on my local server as you can watch [this video.](https://www.loom.com/share/da2f2ae9d3024e6486e8f420baf0c350)
 * It looks like there might have a conflict on your site. So, this will need to
   check if that is coming from any other plugin.
 * Please make sure that you’ve already done the conflict test. If you haven’t yet,
   Please follow the below procedures for testing purposes.
    -  Please deactivate all plugins except the WP User Frontend Plugin.
    -  Use a default theme such as twenty-twenty or twenty-twenty-one.
    -  Use the default language on your website.
    -  Clear your site cache as well as the browser cache and try the process again.
    - But, If you are still having the problem, then kindly contact through [the website](https://wedevs.com/contact)
      for further assistance.
    - Regards!

 * Hi Saidful
 * I double check here and the conflict is with wp super-cache for CF plugin, maybe
   the sweetwater2 library version?
 * Hopefully soon we can get the library update
