Description

The log entry for a protection log generates links with an offset parameter to action=history, but that gives an backtrace on Flow:

Flow should override the protection log entry to point the history link to something that does work.

• DannyH moved this task from Untriaged to Near-Term Interest on the Collaboration-Team-Triage board.Aug 26 2015, 11:48 PM

Maybe it is just an problem by a parameter name conflict (Flow is using offset with other values like core?), in that case Flow has to use another parameter name and Flow has to map the offset value to the correct Flow offset parameter
