We’re on O365 with a 2010 interface still (too much customization on the old 2010 sites). We’re on IE 11, but forced into compatibility mode on all intranet sites. If I rollback DFFS and vLookup to pre-Beta and 4.351 the docIcons work as before.
Currently on DFFS version: Backend v.4.352, css version 4.1/4.10 |spjs-utility 1.25 | [vLookup plugin backend v2.250]
I have made a change in one of the latest versions of vLookup that most likely caused the DocIcon problem. In SP 2013 it is no need to explicitly load these fields, but obviously there is in SP 2010 or “2010 mode” in O365. I’ll release an update during the weekend.
