Attribute rel redefined in Entity - Causing major issues

[Serverhus]

Hi guys,

 

My question is simple, but the reason for it is not. I don't know the hollidays in the US and I'm not sure if support is open. I opened a critical ticket over 24 hour ago without reply (Ticket #823593). So if anyone could let me know if the support is closed or something, that would be great.

 

 

Maybe someone else has had this issue and could give me a few pointers as well. All over my page (admin, client side, E-mail templates etc) i get the error below. I don't believe it's from upgrade to 7.1, but the system has been running without issue for a long time. Now my clients are getting frustrated, and since i do not recive a reply I'm getting very worried. Feel free to look around at https://serverhus.no/Klient
