Extended Player Statistics script error - Better Battlelog Forums #1946

Hi bf3stats-Team
I have add a custom graph for the extended palyer statistics.
I added the following: "weapons.sg870.ammo" but now i know that this graph isn't available I just wanted to try it.
Now everytime the script loads firefox shows me an script error and I have to stop it.
I can't delete this wrong graph because the script is stoppet It's not possible to click its button to disable it.
Is there a way to remove the graph anyway?
Thanks for your help!
