Army Problem too many user attacks?

I am trying to attack people that attacked me today and this is the first time I have been on all day and it is saying that I have attacked them too many times. Is there now a limit as to how many times we can attack someone in a 24 hour time?

Yes there is a maximum of 15 attack to 1 person in 24 hours from each user,I fell this is an appropriate amount, otherwise it could get out of control.There is also a maximum of 10 spy missions on one person during 24 houyrs from each user.Hope I helped
