 * I am getting a select2 error from the installer. Any advice?
 *     ```wp-block-code
       Uncaught TypeError: $(...).select2 is not a function    at DUPX.initJsSelect (main.installer.php:3133:21)    at HTMLDocument.<anonymous> (main.installer.php:3144:14)    at e (inc.libs.js?ver=1.5.12:3:30005)    at t (inc.libs.js?ver=1.5.12:3:30307)

 * Hello [@chamois_blanc](https://wordpress.org/support/users/chamois_blanc/) ,
 * Thanks for reaching out to us.
 * I understand that you are getting the following error from the installer:
 *     ```wp-block-code
       Uncaught TypeError: $(...).select2 is not a function    at DUPX.initJsSelect (main.installer.php:3133:21)    at HTMLDocument.<anonymous> (main.installer.php:3144:14)    at e (inc.libs.js?ver=1.5.12:3:30005)    at t (inc.libs.js?ver=1.5.12:3:30307)
       ```
   
 * This prevents you from filling the installer fields, and breaks the installation.
 * This error may be related to your web browser. Can you please try another web
   browser and let me know if the issue gets resolved.
 * I’m looking forward to hearing back from you.
 * Thanks!

 * Thank you for the reply. I think it was either a permission or a server issue.
   Trying to access the vendor files returned a 500, so it could not load the select2
   library.
 * Closing now as this is not related to the plugin.
