Hello,
I am trying to add field and edit the category dropdown in the documents module and am receiving the error below.

Fatal error: Call to undefined function: return_custom_app_list_strings_file_contents() in /homei/public_html/crm/modules/Studio/DropDowns/DropDownHelper.php on line 86
I just upgraded sugar to 4.5.1e (Build 1049)

Any and all help is appreciated
