Two-factor authentication button doesn't seem to me to be working
Whenever I try to click on the Enable two-factor authentication button in https://translatewiki.net/wiki/Special:Preferences, it leads to a generic "Internal error" page with the content being [ff43c56a3c9d040154209c8a] 2019-06-08 17:54:36: Fatal exception of type "Error" (The hexadec number seems to be different each time, and the timestamp is of course also different each time.)
