Hi after searching a lot I,m posting this question. When trying to add a tag in k2 item in joomla 2.5 backend, nothing happens. I have pressed enter and also tried with comma. I have tried with updating k2 latest version. But still same problem. I,m using ja_wall template, joomla 2.5. Also I,m getting this error after k2 upgrade

Model class cpanelModelCpanel not found in file

Can anyone help please.

There are several posts here about the ModelCpanel, search for it and you will find posts from Lefteris that suggest deleting a file, that was left over from a previous version. Also, the latest 2.6.1 or the svn should have a routine in it to automatically delete the file on install

In my test 2.5 k22.6.1 site the tags function properly by typing a tag and pressing enter.
Back up first and try reinstalling

Hello William

Thanks a lot for your answer . ModelCpanel is not the main issue. According to your words I have uninstalled and installed k2 again. But tags still not works in back-end. After typing process ends and tag doesn't add. I have tried saving and then check but still same. I saw firebug console but no error. Please help . If you want I can pm you admin details

Thanks

Hello William

Please give me a replay :(

Thanks
