For two days when an attack is sent against me

by clicking on the attack, I can not see who is attacking!

the list of the tracking is empty!

I am told that some units are heading for my castle, but nothing!

Impossible to provide a defense or counterattack

For information:

I emptied my cache of the browser, cleaned the cookies, made a total cleaning of my computer, turned off my box, turned off and turned on my computer !!!!!

and .... the problem persists
