Hi,
When I want to delete a topic, I have the loading icon "in progress" (and a error message on the console : error 500 in wp-admin/admin-ajax.php).

The screen is locked on this loading screen. Two possibilities : 

• If I just reaload the page after this, I still can see the topic from the main page but when I click on it, I have a message saying that the topic is deleted. (no fully deleted ?)
• If I click again on the delete button, the topic is correctly deleted.

My WP is the 5.0.3 version. I have disabled all the plug-in and i have found out that the error comes from the BuddyPress (4.1.0) plug-in. If i disable this plug-in, I dont have this error anymore.

Any help to deals with this ?
