[Wzv96gpAICIAAAY@74cAAADI] 2018-07-03 22:51:22: Fatal exception of type "Flow\Exception\InvalidDataException"
after the beta feature was accidentally disabled and then re-enabled.
Hi! Since I switched to beta features including Flow structured discussion on my user talk, everything was well until I turned off it by inadvertence. I toggled again but its triggered into displayed "Fatal exception of type "Flow\Exception\InvalidDataException"" error. Therefore I can not do anything to fix it. Since then neither users nor myself are able to write on my user talk.
Thus, I ask you for help to fix that issue. Thank you very much in advance.
I tried a purge but nothing changed.
I skimmed search results, and this task might contain relevant notes for the devs: T184670: [wmf.16-regression] Fatal exception of type "Flow\Exception\InvalidDataException" for opting out from "Structured Discussions on user talk"
