Hi everybody, I've just installed the new 3.0.5beta1. Afteer a few days now it seems to work correctly. It runs through a virtual machine with 2 processors and 2 Gigs of ram. ClamAv and ntopng are stopped (ntopng is a RAM waster!). Browsing is fine now, but I absolutely cannot download anything: every file I try to download, starts and after a few minutes the download drops. In the configuration, I put "0" in the fields of "dowload dimensions".
What can I do?

Thank you in advance
Evh

mmm. more info: It depends to the proxy type: if I use non transparent the download is fine, if I use transparent proxy I cannot download files...Any Idea?

You mentioned it's on vm make sure your networking in promiscuous mode
