Notice: Undefined index description taxonomy_form_term_submit_build_taxonomy_term(), line 842 of taxonomy.admin.inc

I have received the same error notice, but I am too new to all of this to know exactly what it means. I got the message after I said "set multiple parents" for the last taxonomy term I entered. I don't know what the drag and drop interface is, but I was ok with doing without it because I need multiple parents for terms.

Would any of the more experienced people be able to help me understand what this means and how I would fix it if it needs to be fixed? I appreciate any help.

If this is important to the problem, I am running Drupal 7 from a MAMP local environment just for testing it out. However, I would guess it is more to do with my multiple parents thing.

I also received this error message after enabling Multi Parenting, but it also said 'Updated term a term' in a green alert box. (D7, XAMP Lite)

When enabling Multi Parents, Drupal warns that the drag&drop sorting function will be disabled. But afterwards, the drag&drop arrow icons still show. Dragging still is possible, dropping is not (javascript drop event seems not attached). The Save-button does not show.

Then: Root can be selected as one of the parents. When doing so, the next time you open the term's admin page, all parents but Root are selected!

I just got the same error when using multiple parents on a term.

I get this error when enabling multiple parents on a term also.

I'd also echo #2 by saying that the Drag continues to work after enabling multiple terms and only the Drop is disabled, which is a little odd.

This sounds like a duplicate for #949616: Multiple parent relations confirmation form loses term description.
