After upgrade nothing except GET requests work - 422 error everywhere

[Vladimir Lelicanin]

Hello, 

I have upgraded Canvas to the latest version and since then only GET requests work. Every time I try to delete, or post I get an Invalid token and 422 error (like some people complained for File uploading, but for everything across the system). I am not Rails developer but I was inspecting the code and basically everywhere where verify_authenticity_token is used it fails. 

| tried everything I could think of, form setting crossdomain.xml, modifying header... no luck!

If you have any idea, please help. 

PS. Everything is on the same server. 

Regards, 

V.
