Should Who Visited My Profile work on CB 1.9.1?

I have installed this extension on CB 1.9.1 but it does not seem to work, should it?

Well as you can see it is working with CB2.0 on J3 as here (bottom of your own profile)
Make sure in the plugin params, you have a limit set (at least 30 days)
Also note that for stats rendering plugin should ne be tabbed.

I do have a limit set of 30 days so maybe it is not compatible with 1.9.1
It is not tabbed

Also check in your own profile edition the value set for that limit
It's empty for me in this site, but maybe an incorrect value would prevent it to work correctly.

I'm currently reviewing the code, I don't find anything that would not work with CB1.9.
Also on plugin installation a query is run to add a new table.
Check if #__cb_profilevisits is created successfully and eventually populated when having a new visitor.
