After updating K2 I get this message "Model Class "cpanelModelCpanel" in file not found!" (hope the translation is correct.

Few things in front end don´t work anymore.

I need a quick solution.

Thanks

Yep, I get the same. The problems I see locally are these -

1. The T&Cs item ID for K2 Store now returns a 404 error
2. The attachments folder setting is ignored, and attachments now all return "File not Found" errors
3. Uploading new files seems to complete okay, but the file is nowhere on the server. I have no idea where it goes.

Using 2.6.0

There are at least 3 recent posts regarding the issue. Is it so hard to use search?

None of which describe front end problems also being introduced.

I've deleted cpanel.php, but my issues persist.
