Doors Dissapeer when opened!

Help me!
I have been really sick lately and have not been able to get on my server.
Now i am back on when i open doors they comepletly disapeer.
This is on RP.
This bug is server side.
I am running Dark RP 2.4.1
But trust it to mess up when i am in desprite need of it working!
Why is this?
I really need this fixed.
