Cannot quote?

if I try to quote a post, I get the loading icon thingy, it just keeps on spinning and spinning, but I never get to actually post the quote or get the option to paste it in a message?

Can anyone tell me wassup or what I can do to fix it?

Click on 'Reply' on the post. Click on 'View source (ctrl+shift+s)' on the bottom of the menu.

Not hard to figure out.
