After adding a new blog to my MU installation I changed the browser path in the configuration page of the new blog. That caused the loss of browser function (no dirs show in the file browser) and also the downloads on the main site don't work anymore.
We're having big problems now since a new web campaign is driving a lot of visitors that register to download our files.
I hope we can get a reply very soon. We are in deep Sh..!
THanks!
