Hello i can't delete or invite nobody to my clan, first i thought there was a bugg that needs to be fixxed, but the problem is still there after a few months.

I have people that want to join my clan and every time i go to my clan HQ then click to manage there is always a error when i want to inv or delete peepz why that? I tried several browsers I.E/Chrome/Firefox/Maxthon3 so i know thats not the problem. I'm was a founder member since MW 3 and know how the site works even the Elite 2.0 version this is something else.  I went to a few friends house and tried it over there still same error i can't do nothing about it can somebody help?!
