and following the unsuccessful plugin update . I can’t view the site anymore , as I get this Fatal error
Fatal error: Call to undefined function bp_page_title() in …../wp-content/plugins/buddypress/bp-themes/bp-default/header.php on line 9

where do I start ? update-notification.php or somewhere in a config ?

Sounds like you’re using an older version of WordPress.

BP 1.2.7 requires at least WP 3.0.

Via FTP or your control panel rename jet-events to disable it to allow you access once again.
