I have been having problems with clickable icons for the past couple of days. For starters, I sometimes cannot deposit or withdraw from my gang vault. When I click, the link highlights in orange like this:

I don't get the "you need $100 per item to deposit" message, refreshing doesn't work (someone suggested that, can't remember who), and no one else seems to have this problem. It didn;t bother me much, but now, I can't erase my mail! When I try, it highlights in orange the same. 

Again, I don't have the message that says "Are you sure, because we won't ask confirmation again" warning. 

My browser is Chrome, if it helps any. And I am very sorry if it's not a bug. No one else seems to have this problem.

Do you have JavaScript disabled? Seems like that might be causing it.

Yep, I think that was the problem. Sorry. And thank for your help.
