Unable to trade with fellow premium member

Hi everyone!

I am currently experiencing issue with one of my friend. We are both premium member as of today. We were looking forward to trade some items together but we both get this message when trying to trade :

"There is currently a problem with the selected function Use is restricted for investigation Please check the player's site for details."

I've checked the official website, read the recent news.... Still no clue as to why we are getting this error. I've check and search around the forum ; still nothing. I'm not used that much about community website and such things so I am terribly sorry if there was official announcement regarding this but i never noticed it.

Thank you in advance for your help.

Thank you for the reply. Guess I'm still not used to search the website properly. Well, it now gives me a reason to hate these bots even more now!
