Publish button not working

Hi, 

I configured user_wordpress with owncloud 6.0.3 and now I'm able to use my wordpress (multisite) 3.9.1 users in owncloud. 

However, I'm not able to publish files as when I click on the "Publish" button over a file, nothing happens. I guess a script should activate and open a widget. I tried with different browsers with no results. 

Could you please help me track the problem?

Cheers
