[Plugin: WP User Frontend] Image uploading only succeed if user is admin

I got the same problem.
Does anyone find a solution for this?

Not yet… No idear what happens and I really don’t want to add 700 users to my “user frontend ” blog as editors to let them upload images. ??

I got exactly the same problem. Any information about that?

Maybe it’s not really hard because in my case, pictures are uploaded (you can see them in the website files), but not “linked” with the post. I work with custom posts, maybe the problem come from here.

This problem is also related in this topic.

Thanks by advance if you have any clue about this problem.

ok I just discovered that the problem can come from a security fix from the new version of wordpress, 3.4.2 or 3.4.1. Maybe it’s not from the plugin.

In my side, the problem occurs because I blocked access to some admin menu and submenu pages to editor roles and beyond, using remove_menu_page or remove_submenu_page.

The warning I got when I tried to add a picture with a non-admin role:
<b>Warning</b>: Invalid argument supplied for foreach() in <b>/homepages/13/d385045163/htdocs/wp-admin/includes/plugin.php</b> on line <b>1286</b><br />
(This line refers to remove_submenu_page function)

The JSON query was stopped (syntax error) because it received no response when it asks the uploaded file to be attached to the post (line 68 of attachment.js). Maybe some of the blocked pages are required to attach media to the post in the media section.

I removed remove_menu_page functions in my functions.php file and it worked again. Hope it can help you.
