ShoutBox Bug

Hi guys !
So today I installed a PirateBox on my Raspberry Pi (Jessie Light) and everything works great... Except the shoutbox!
When i try to send a message, the button still on "Sending..." state. I checked logs, break.log and nothing is wrong. I tried to run the psowrite.py in the cgi-bin directory but i had an error. I searched on forums for an answer but nobody seems to have this problem.
Thanks for your attention & sorry for bad english!

Hi,
I am sorry to hear that you have an error.

Do you think you can post the error message?
Do you find an error.log inside /opt/piratebox/tmp ?

Best regards
Matthias
