The entry for infinity-field seems to work for me (ncatlab.org/nlab/show/infinity-field). Could you check and, if the problem persists, give the specific URL that produces wrong behaviour? Thanks!
I did have a question though: When people in here are talking about L_infty algebras, is there a simple description of the \infty-operad version (I guess this is the version in spaces)
@UrsSchreiber Yeah, but it uses all of the species stuff. I was wondering if you could make sense of the Lie Operad/L\infty operad in something like spectra or spaces
