"Events not enabled." when accessing Statistics

Hello everyone,
I am experiencing a bug in Seatable 1.6.0.

When I open admin settings and then click on “Statistic” I get a popup saying “Events not enabled.” and the screen keeps loading.

The browser console has the following issue:

domain.com/api/v2.1/admin/statistics/active-users/?start=2021-01-10 00:00:00&end=2021-01-16 00:00:00 returns an error 400.

dtable_web.log has the following:

2021-01-16 16:11:01,885 [ERROR] seahub.api2.endpoints.admin.statistics:136 get Invalid URL ‘/admin/statistics/scripts-running/by-user/’: No schema supplied. Perhaps you meant http:///admin/statistics/scripts-running/by-user/?

Is this a known bug or is it just me?

Thank you

This is likely to be a bug. We will check it.

I would like to note that I saw this on 1.5 too.
