I've had a look at some wikis (en.wp, pl.wp, pt.wp, fi.wp, he.wp) where ORES is deployed by default, and none of them are impacted. It seems to be a Wikidata specific issue.

Maybe because of Wikidata already has 1.30 whereas Wikipedias have still 1.29...

We're going to have a loop asap!

I'm not sure: he.wp is on Wednesday's train and is not impacted.

I will look into this but I can't promise if I can get it working since the codebase has been changed a lot by the collab's team

Collaboration team developers will be online in a few of hours. I've warned them about this task.

Maybe a side effect: it is not possible to change the interface language on Wikidata anymore. Still possible on Commons. (Report)

[operations/mediawiki-config@master] Set oresDamagingPref default to values that actually exist

https://gerrit.wikimedia.org/r/353311

Well, I was working on it but I will happy to help and collaborate. What I've got so far is that hewiki is okay even though their configs is almost identical and both are on wmf-30.1

I think it's because Wikidata's default sensitivity is set to 'hard', but the corresponding damaging level ('maybebad') is set to false in the threshold settings. No other wiki had this problem except fawiki, which is in group2, and this only started mattering with rEORSc047cd54d69e: Align damaging thresholds to filters thresholds which is in wmf.1.

Okay, I get your patch deployed ASAP.

[operations/mediawiki-config@master] Moving some ORES configs from InitialiseSettings to CommonSettings

https://gerrit.wikimedia.org/r/353344

This new config is causing a huge logspam of "Notice: Undefined variable: wmgOresDefaultSensitivityLevel in /srv/mediawiki/wmf-config/CommonSettings.php on line 33351" because I think CommonsSettings.php is being ran sooner than IniritalizeSettings.php
