There is a problem with the SSL certificate for your site.
The url you posted does not go to a secured site.
Re invitations, the url would be: https://url.eu/members/jberger/groups/invites/
		
	 
	
	
	
 
		
			
	
	
		
		why does it look like this at my page then? /members/jberger/invitations/ If it should just be called invites? Any idea how to fix that? 
Thanks in advance!
		
	 
	
	
	
 
		
			
	
	
		
		I don’t know.
Does the url I suggested work?
Did you try editing your url?
How is your url being created? 
		
	 
	
	
	
 
		
			
	
	
		
		Yes, it does. 
But I don´t know how to make it right. I don´t know how it is created, I use standard buddypress setup. 
Anyways: invites are part of the notifications. Is there a possiblity to remove the invitations link from the object-nav?
Thank you a lot for your help!

That is not part of a standard BP setup.
So there is some issue specific to your site – perhaps caused by your theme or some other code or plugin.
