I\'m trying to install berta (v 0.6.3b) and I get this error:
Warning: session_start() [function.session-start]: open(/var/php_sessions/sess_a0d6b84
If you're changing the path that is being used for sessions.
You also might consider, fixing this problem by changing session.save_path variable in your php.ini file.
session.save_path
php.ini
Then you'll be fixing in your configuration file and not only in your script.
