 * Hi there,
    I tried this plugin and seriously loved it. Tweaked it. Then when 
   activating notifications, bell loads and loads. Console has these two errors :

 * I don’t know what to do.
    If you guys have a solution, I would love to reactivate
   this plugin and continue with it. Thanks a lot.

 * Hi,
 * Do you still have this problem even after uninstalling and installing the latest
   version?
    If you’re using the logged-in bell, you can contact me here: [wpnotificationbell@gmail.com](https://wordpress.org/support/topic/error-500-admin-ajax-php-error/wpnotificationbell@gmail.com?output_format=md)
   with how to access the website so I can look into it.

 * Hi there, thank you so much for your help on this matter.
    I uninstalled and 
   resinstalled it. I activated options one by one and found out that “Enable BuddyPress
   notifications (logged-in users)” option is the one making this error. I don’t
   know why (I actually use BuddyPress). Do you have any idea by chance? I’ll make
   a staging site in a few days and give you access to it. Thanks.

 * Hi,
 * I just released an update that may fix the issue. You can test it out and let
   me know if you still have the same problem.
