Maybe this issue is connected? http://wikirate.org/Walk_Free_Foundation+MSA_risk_assessment+Swarovski_AG+2017#

This value is not citing any source, when trying to cite one and clicking submit, I get a wagn hitch. For the example above (Rolls-Royce) I was also trying to cite another source (changing one out for the other) and then getting the wagn hitch so maybe the source citing is the cause of the problem rather than the new value options (which I suggested above)...

still happening.

Actually, I wasn't seeing the hitch any more, but it was still failing. Then when I tried by adding ?view=edit directly, it worked (I fixed the answer).

I think I'll close this ticket, because the the local problem is fixed and the broader problem is probably unrecognizable now. But it's a priority ticket for us.
