 * Hello,
 * I have downloaded the plugin and it is a wonderful job is coupled to what you
   want on my website. But the following happens. when I try to create the activities
   and click on ok, it does not save and does not load, in the browser console it
   shows the following :
 *     ```

 * Hello, thanks a lot!
 * There may be a conflict with one of your plugins or your theme,
    Can you follow
   the instructions below “Booking Activities doesn’t work as it should” here in
   order to identify it: [https://booking-activities.fr/en/documentation/faq/](https://booking-activities.fr/en/documentation/faq/)

 * Hi, yes, I have deactivated my other plugins and left only the scheduling plugin.
   But the browser console shows the error directly from the plugin folder:
    [https://prnt.sc/LED9PXWrSPZE](https://prnt.sc/LED9PXWrSPZE)
 * In the faq you share with me I don’t see anything close to fix it. Can you guide
   me in the process of solving it? My current php version is 7.4 and as I said 
   before WordPress runs under version 5.9.3.

 * Can you
    – go to WordPress general settings (Settings > General) and Save (even
   if you change nothing), and try again? – go to WordPress general settings (Settings
   > General), change the Site Language, Save, and try again?
 * Indeed, I can see on your site source code that code:
 *     ```
       <script id="moment-js-after">
       moment.updateLocale( 'en', {"months":["January","February","March","April","May","June","July","August","September","October","November","December"],"monthsShort":["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"],"weekdays":["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"],"weekdaysShort":["Sun","Mon","Tue","Wed","Thu","Fri","Sat"],"week":{"dow":1},"longDateFormat":{"LT":"g:i a","LTS":null,"L":null,"LL":"F j, Y","LLL":"F j, Y g:i a","LLLL":null}} );
       </script>
       ```
   
 * As you can see, the locale is “en” istead of “en_US”, it means that your site
   language has not been properly set.
 * The issue has been reported [here](https://core.trac.wordpress.org/ticket/52695)(
   the following parameters should not be null: ‘LTS’, ‘L’, ‘LLLL’). This bug should
   be fixed in WordPress 6.0 ([planning](https://make.wordpress.org/core/2022/03/11/wordpress-6-0-planning-update/)).

 * Hello, me again. What a pity to be so annoying… I just dropped by to tell you
   that it worked! 😀 I carried out the first recommendation:
 * “– go to WordPress general settings (Settings > General) and Save (even if you
   change nothing), and try again?”
 * By doing so, the calendar was displayed and I was able to generate the activity.
   I appreciate the support and thank you for developing this plugin.
