Actually the issue also impact other reports that show "Clicks" instead of "Visits":

at https://demo.matomo.org/index.php?module=CoreHome&action=index&date=today&period=week&idSite=62&updated=2#?idSite=62&period=week&date=2020-02-01&segment=&category=Referrers_Referrers&subcategory=Referrers_WidgetGetAll

or event the Visits log seems broken:

@mattab this is only happening for ProxySite as mentioned the other day. Not for a regular site.

BTW It looks like this regressed as part of 3.13.1, not 3.13.2 still looking into things

FYI @diosmosis it is caused by 2915d75 the change from disable_datatable_post_processing to disable_root_datatable_post_processor https://github.com/matomo-org/matomo/blame/3.x-dev/core/Plugin/Visualization.php#L336

and I think as a result column names are not replaced for example but I suppose this might be only one of the side effects. Can you maybe have a look?

@tsteur / @mattab Oh yes, I noticed this, I have a fix (applied to demo) but I'm not sure if there will be any side effects. ProxySite's UI tests aren't working anymore (possibly due to 4.0 in some way).

👍 I think eg the actions report does now show data. The visitor log still doesn't by the looks? https://demo.matomo.org/index.php?module=CoreHome&action=index&idSite=62&period=day&date=yesterday#?idSite=62&period=day&date=yesterday&segment=&category=General_Visitors&subcategory=Live_VisitorLog

BTW not sure it is a side effect or related... but looks like maybe sorting doesn't work correctly anymore?

Seems to be sorted by label instead of unique visitors?

That's annoying, too many side effects. The issue is that Archive.php queues some filters to every report, but w/ disable_root_datatable_post_processor, they are no longer applied in the target. Removing disable_root_datatable_post_processor would of course break something else. I wonder if we're at the limit of what ProxySite can do given matomo's current architecture.

Yeah that's possible. Not using disable_root_datatable_post_processor was breaking some comparison feature I suppose?

Yes, possibly pivotBy too. I can't remember the details, but they involved ViewDataTable and were somewhat confusing.

The demo now looks good and working, even sorting seems to work for me?

Thanks!

@mattab I only modified some code in demo, it will require a PR, but I found another comparison issue locally.
