[SOLVED]

Hello,

Christian, from Belgium. I use K2 for a long time, it is the only good free tool to manage an item. Thank you!

I would contact you because I have a problem with K2.

I develop a Joomla extension that I want the system compatible with K2, because I think your brilliant concept!

Articles must be imported into K2 from an external source.

Currently, the import completes successfully but in FRONTEND, I get this error: "Fatal error: Call to undefined method K2ModelItem :: getUserProfile () in / home/www/fashion/components/com_k2/helpers/utilities.php it line 63 "and a blank page.

I use the class ". ModelItem :: save" slightly modified. (Item entire model is imported into the extension).
In the database, everything seems OK (I compared with native recording) FRONTEND but nothing works.

Could you help me and tell me what I missed please?

Thanking you in advance.

Here k2 modified class I use:
