Hi, I´ve tried all possible combinations of Media and File Entity modules:

Media:
7.x-1.4
7.x-2.0-alpha4

File Entity:
7.x-2.0-beta1
7.x-2.x-dev

And everything installs fine, but when I add a MD Slide, I cant add any image or text. When I try to save it (empty of contents) I get this error message:

Warning: Invalid argument supplied for foreach() in md_slider_edit_form_submit() (line 630 of /home/*****/public_html/drupal7/sites/all/modules/md_slider/includes/md_slider.admin.inc).

Any advice?

Thanks
Miguel
