I have a few catagories on the site where extra fields are required. On the front end I get this text "The following fields are required" if they aren't filled out. I want to change that text but I cannot find the file its located in. Could someone point me in the right direction?

try editing
siteroot/administrator/com_k2/language/en-GB.com_k2.ini
line 911
K2_THE_FOLLOWING_FIELDS_ARE_REQUIRED="The following fields are required"

Those file directories don't exist, there is no com_k2 folder in the administrator folder. There is a joomla\language\en-GB\en-GB.com_k2.ini but that doesn't have the text in it. I am using Joomla 2.5 and the latest version of k2.

Hi,
I just checked in Joomla 2.5.8, and you can change the text in Extensions / Languages / Overides / then change to site or administor as needed. then.
Language Constant = K2_THE_FOLLOWING_FIELDS_ARE_REQUIRED
Text = Your required text
