Any explanation? As you can see I had no trouble editing this item.

I was not able to edit and this was corroborated on IRC
Thanks,

Gerard

[09:30]GerardM-is https://www.wikidata.org/wiki/Q6523958 not editable ?
[09:31]GerardM-if so why, if not why can I not edit it[09:35]GeorgeEdwardC

ircs://freenode/GeorgeEdwardC,isnickStrange that it can be edited by
tools, but not by the usual interface

Do you get edit links or not?
Does opening https://www.wikidata.org/wiki/Q6523958?action=purge change anything?
Does it work logged out?

Hoi,
At the time it did not work for anyone.. Now it does..
Thanks,

It happens quite regularly that things should be editable and are not for reasons that I cannot determine.
