Due to bug 47457, the Wikimedia Foundation is immediately disabling the WikiLove extension on all Wikimedia projects until the underlying issues with mw.loader are resolved. The following projects had WikiLove enabled and are thus about to be affected:

arwiki commonswiki enwiki fawiki fawiktionary hewiki hiwiki huwiki incubatorwiki iswiki itwikiquote itwikivoyage jawiki mediawikiwiki mkwiki mlwiki nowiki officewiki orwiki ptwiki sewikimedia siwiki srwiki svwiki svwikinews trwiki urwiki zhwiki

It will remain enabled on test.wikipedia.org for testing.

During this outage, no one will be able to use WikiLove to give or receive comments, but all existing WikiLove talkpage entries will remain.

We hope this outage will only be for a few days, but we don't have an estimate on when it will be resolved yet. Please help us to spread the word to the projects that will be affected. We can respond to comments and inquiries at the Bugzilla bug: https://bugzilla.wikimedia.org/show_bug.cgi?id=47457 (People using Firefox can't load user and user talk pages).
