I have just upgraded to Plesk 7.5.1 and noticed the following error: client A does not use much in his main account, around 1Mb. But he uses a lot with one of his web users (like 56Mb). Unfortunatelly Plesk reports, that 58Mb is used by http docs AND 56 by webusers with 112Mb in total! I checked with "du -hs" in his home directory - still get 89Mb in total, and not 112!!! What's that?! In Server Preferences I have got When calculating disk space usage, count - file size.
