 * Hi guys,
    I have problem with your plugin last few updates (maybe? not sure) 
   in combination of plugin Custom Post Types ([https://wordpress.org/plugins/custom-post-types/](https://wordpress.org/plugins/custom-post-types/)).
 * With combination of these plugins I get error with JQuery:
 *     ```
       load-scripts.php?c=1&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils,regenerator-runtime,wp-polyfill,wp-hooks&ver=5.9.3:2 Uncaught TypeError: $ is not a function
           at u (backend.js?ver=5.9.3:14:75235)
           at HTMLDocument.<anonymous> (backend.js?ver=5.9.3:14:79046)
           at e (load-scripts.php?c=1&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils,regenerator-runtime,wp-polyfill,wp-hooks&ver=5.9.3:2:30038)
           at t (load-scripts.php?c=1&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils,regenerator-runtime,wp-polyfill,wp-hooks&ver=5.9.3:2:30340)
       ```
   
 * Because of this, the other plugin needing JQery to work, have problems (in administration
   part only as I can see) – Custom post types, Loco translate too. It happened 
   on both site where the plugins were installed together.
 * There is no caching on the web, I cleared the cache of the browser, but notning
   helped.
    Running on WP 6.0.0, these two plugins are on the last version.
 * Could you help me to solve this?
 * Thank you
    J.

 * Hi [@jitka88](https://wordpress.org/support/users/jitka88/) ,
 * Thanks for reporting this to us!
 * I’ll be sure to create a report regarding this so our developers can check what
   we can do from our end to avoid such conflicts.
 * Meanwhile, I will also recommend contacting custom post types plugin support 
   to let them know about this as well. Kindly let us know if they can provide any
   information too about this.
 * Kind regards,

 * Hi, the configuration is:
    WP core_ 6.0.0 PHP 7.4.30
 * plugins:
    – Custom post types 3.0.11 – WP User Manager Version 2.8.5 (rest of
   the plugins were deactivated)
 * It seems these two plugins don’t like each others.
 * Do you have any ideas?
    I contacted the second plugin too, but no news from them.
   I’ll let you know immediately I’ll have some news from them.
 * Thank you
