Not working

Hi,

I don't know what happened, but the "Ask Question" and the "Submit Answer" button doesn't seem to be working. After we type the question or answer and click on "Ask Question" or "Submit Answer" it doesn't do anything. No wonder we haven't been receiving questions from some weeks.

I checked and saw that there was an update version (I was using 1.7.3) and I updated to 1.8.1, and it still doesn't work.

HELP!

Regards,
Faraz
