Fatal Error in Front end using Standard Gallery Shortcode

[christopheranderton]

Getting:

Fatal error: Call to undefined function get_grid_classes() in /dev/wp-content/plugins/twitter-bootstrap-galleries/twitter-bootstrap-galleries.php on line 289

This happends when using [gallery columns="4" link="file" ids="519,518,517,515,514,513,512,511,510,509,508,507,506,505,504,503,502"] in a post (Gallery Post Format and Standard Post in this example). The error message is at the front end.

This shortcode is a standard Gallery shortcode generated by WordPress. Did save the settings in the Plug-in Admin before inserting the shortcode.

WordPress Version: 3.7.1 local install (MAMP).
Themes tested on (All up to date): Pink-Touch-2 (fork), TwentyTwelve, TwentyThirteen, SemPress

Debug is set to = on
PHPMem: 256mb
Active plugins (only dev): CodeStyling Localization, Developer, Log Deprecated Notices, Log Viewer, Regenerate Thumbnails, Simply Show IDs, Theme-Check, Theme Mentor, User Switching, WordPress Import.

Cheers.

@Deluxive Thanks for posting your issues and your detailed report.
Could you verify the latest version from https://github.com/bassjobsen/twitter-bootstrap-galleries/archive/master.zip still got this error. Cause your error report mention line 289 while get_grid_classes will be called in line 285.
Thanks!!
