I am having a problem with "new item" link in SharePoint 2013 lists. A month ago client found that when they are in a list page (AllItems.aspx) with additional document library webpart at the bottom, they cannot create list item when they click on new item (actually they do not see new item, but "new document" link), because somehow new item link has been rendered as document libraries "new document" link.
How can it be??
From inside server everything is alright and list has "new item" link while document library web part has "new document" link, but users which are connecting to SharePoint not from inside server they are facing this problem.
I have already asked what version of Internet Explorer they are using. All users use IE9. Also I asked to change IE compatibility view, to render pages as IE8, IE7 and other options (all options actually)! Non of them helped. Is it a problem with IE or is it a problem with SharePoint rendering html?
What possible work-arround or solution could you recommend?
