When I install EP any version (I have tried all from 2.78 upwards) then none of the download links do anything on the admin page. When looking at what the php is doing I see that $download and $dltype are always blank even though I can see their values in the query string. I this something to do with me being forced to run with registar_globals OFF (there was another contribution that fixed this)?
Cheers!
