drag&drop should work. Can you manually create a new item in the group library? Of any type?

as I said - of course you should be able to drag & drop. This was just to see whether you had the general permission to add items to the group library.
Create a new item in your library and the provide a debug ID for trying to drag it to your group library (and presumably failing)
http://www.zotero.org/support/debug_output

you enable debug output, then you perform the (failing) drag&drop action, then you go back to the preferences and click "submit to Zotero Server"

when I say "provide" I'm asking you to post the debug ID here so that devs can take a look at what happens. As per step 4. of the instructions:
"Zotero will provide a Debug ID that you can post to the forums"

Re-installing Zotero is unlikely to help.

If you can't drag an item in, it's because either you don't have write access to the library or because a previously dragged copy of the item is already in the library (even in the trash).

In this case, it looks like you don't have write access to the library. This is why adamsmith asked if you could create items in the library. You said you could, but did you actually try? Based on the current permissions, you wouldn't be able to. Your colleague needs to fix the editing permissions on the group from the website, and then you need to sync.

you've made sure the two issues that Dan mentions don't apply?
I.e. you can add new items to the group and none of the items in the collection has previously been included in the group?

What's the problem, exactly?

I have my library open in the tab below and my group opened in Firefox

Are you saying that you're looking at your group on zotero.org? If so, that's completely separate from the Zotero client. You can't drag to or from the website. You can only drag between libraries within the Zotero client.

- Go to the group settings page here on zotero.org
- click on "Library Settings"
- Set "Library Editing" and "File Editing" to "Any Member"

I can't create individual items in a group or drag items within Zotero standalone into the group, but I can create individual items on the website. At an earlier stage, the group was not set with "File Editing" to "Any Member" but it is now. Debug ID D809876412

Hi
sorry but I didnt understand what to do eith the ID
"Zotero will provide a Debug ID that you can post to the forums"???
and the drag and drop didnt work to.
I'm asking for help and thankyou

same problem... everyone has admin privileges but looking at the zotero client (add on for firefox), one cannot drag a file from the personal library to the group library. It works fine on the laptop of the original admin, but not on my desktop, even though i am listed as an admin. any suggestions or solutions yet? cheers,

actually yes, i just solved it (my version of the problem anyway).

Did so by changing the permissions so that “any group member” can edit the library – as opposed to only admins. So even though we were listed as admins, the system wasn’t allowing us to update... now that it allows regular users to update, i am able to.

not sure if this will help the above posters or not! but good luck,

I am having the same problem. I created a group. Then I mistakenly added items to my library, when I should have added them to my GROUP library. How do I move them from library to my group library? I should have permission since I created both. Thanks.

Nothing. They stay put, and are not added to the group library. But I am probably doing it all wrong. I've just started using this tool. Cool tool, by the way.
