[Plugin: WP Super Cache] Error(s)

I just updated WP Super Cache few minutes ago.
And i have this error message saying:

Warning: Division by zero in /home/****/public_html/****/wp-content/plugins/wp-super-cache/wp-cache.php on line 1745

And also, i notice that its no longer to have a way to connect “bad behavior” and “no-adverts” plugin in the latest version of super cache. I tried to uninstall the plugin via uninstall.php, but i also got an error message saying:

Warning: Cannot modify header information – headers already sent by (output started at /home/****/public_html/****/wp-content/plugins/wp-super-cache/uninstall.php:6) in /home/****/public_html/****/wp-content/plugins/bad-behavior/bad-behavior/screener.inc.php on line 8

Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /home/****public_html/****/wp-content/plugins/wp-super-cache/uninstall.php:6) in /home/****/public_html/****/wp-content/plugins/si-contact-form/si-contact-form.php on line 940

UNINSTALL_WPSUPERCACHE must be set to a non-blank value in uninstall.php

i really need help regarding this difficulties..
