Undefined function causes error when using mobile Safari user agent

Attempting to load a Wordpress page with the Benjamin theme and the Franklin plugin installed causes an error. The issue appears to be that benjamin_get_cpts() in columns.php is undefined. Stack trace below.

Can you describe the conditions for this error in a little bit more detail. Specifically:

• Is this "WordPress page" a page on the front end, or a post, or is it a custom post type page/post?
• The page/post in question, what was in the content? a columns shortcode or did the page use a template which included a horizontal sidebar?
• Did you download Franklin / Benjamin from Github or from the WordPress repo?

[stevenbuccini]

• The "WordPress page" is the standard WordPress error page that happens when you get a 500. It says something like "This site is experimenting technical difficulties."

• This occurred for both a home page and a custom page we were using (one of the template1.php pages included in the Benjamin theme. I believe both of these pages use a horizontal sidebar.

• I downloaded Benjamin off of GH because we were modifying it and uploading it back to WP as a zip. Franklin we downloaded through the WP package manager.
