Hello guys,

i recently have upgraded my k2 component to my local system (http://localhost/joomlasite). Everything worked just fine so i just moved files (ftp) and database (export->import) to my online development site (www.bluetree.gr)

My local installation works just fine BUT i have a major problem to my online dev site. When i try to select one of the following:

administrator -> Components -> K2 -> User Groups
administrator -> Components -> K2 -> Extra Fields
administrator -> Components -> K2 -> Extra Field Groups

i received the corresponding errors:

Warning: require_once(/home/bluetree/public_html/administrator/components/com_k2/controllers/usergroups.php) [function.require-once]: failed to open stream: No such file or directory in /home/bluetree/public_html/administrator/components/com_k2/admin.k2.php on line 118

I also tried to re-import the database to another online installation but the same problem occurs. Anybody has an idea?

rename the files extraField.php and extraFieldgroup from capital letters to lower case in directory administrator/components/com_k2/controllers

F = f


good luck

Thank you for the advice. This solved my problem after I moved my site to the production server. userGroups.php & extraFields.php had this problem . After I changed the two file names it to lower case K2 was working again. Thanks!
