Error while trying to log into auralmoon - what this mean ?

[DanDare]

Hello guys,

Sometimes i got a message while trying
to log into auralmoon main page, the error is: "In order to accept POST request originating from this domain, the admin must add this domain to the whitelist."

It brings me out curiosity because i host a webserver registered domain in this machine i use.

Should i care about? or it just happens ? Or what what?

Thanks
