Endless loop (sort of)[SOLVED]


At one of the cellenges (“Sum All Odd Fibonacci Numbers”) I wrote a recursive fibonacci code,
This test been made fibo(400000) (sort of) and the page stuck cecaise the number is to big for the program to calculate.
Every time This page (“Sum All Odd Fibonacci Numbers” challenge page) in load it stuck because I believe it run the program automatically.

So my question is: Can anyone tell me please how do I make it work again?
Can I return it to the way this page was from the beginning?

Thank you
