There should be several new pages, the one to add a language is located at: index.php/dashboard/system/multilingual/setup

if you do not see it, go to /index.php/tools/require/upgrade and click the little blue link to force an upgrade, then hit the blue button to upgrade.

I did that (for once it went without hitch) and I got a message saying the update was complete.

But nothing - no change
I then overwrote the concrete directory with the 5.7.3 version and deleted the ones in the upgrade directory - still nothing.

I think the problem is trying to develop on a LAMP stack - there are problems with ownership in Linux which I don't quite understand - I've discovered a file /application/config/generated_overrides/concrete.php which still refers to 5.7.2.

When I do /index.php/tools/require/upgrade I get file does not exist.

When I can find the patience, I'll do a fresh install

Looks like this is a bug. I'll submit to bug tracker.

Just submit it to bug tracker

If you upgrade from 5.7.2, the page won't show up... so it's probably the upgrade script missed to install the multilingual dashboard page.
