Hi
I upgraded a site from 5.3.3 to 5.4.0.5 and all has gone well except now when I try to view any sub-page from the dashboard I see either no data at all (and the page takes on the current theme) or the page uses the 'default' theme - not the usual dashboard layout - and the Edit Page button in the C5 bar is available.. very odd.

Initially after upgrade I was getting 404 errors - trying to find view.php - but the path was referring to a previously installed theme folder.

I suspect there's maybe a reference in the database that's mixing things up.

I deleted the concrete folder and re-uploaded today and initially the dashboard sub pages worked fine, but not long afterwards the symptoms above are showing.

Any help where to look/check would be much appreciated.

Cheers,
James
