    When I try to install this plugin on WP 3.5 I get several error messages, the first one says “Warning: Missing argument 2 for wpdb::prepare(), called in C:\wamp\www\coachkranglin\wp-content\plugins\booking\lib\wpdev-booking-class.php on line 1252 and defined in C:\wamp\www\coachkranglin\wp-includes\wp-db.php on line 990”.

    Sorry for that we will fix the compatibility with WordPress 3.5 during 24 hours.

    If you are made the update to the WordPress 3.5 and right now is see many warnings, please rename the booking calendar folder, using the FTP.
    Its will disable the plugin until the new update will come.

    Kind regards.

    Please update the Booking Calendar to the version 4.0.2 – its have to be compatible with the WordPress 3.5

    I have the same error using the Sharebar plugin. Until the developers update their plugins try this in your function.php

    ini_set( ‘display_errors’, false );
    error_reporting( 0 );

    It stops error mesages and once the plugin devs update- just remove the code.

    Worked over at I hope this helps
