The issue really seems to be related to running wordpress from “/something/” instead of /.
I can confirm I have the same problem on a Linux Centos system with cpanel. The total cache minify doesn’t work on a wordpress subfolder with the latest version of total cache (0.9.2.8). I confirmed this also with a new installation of wordpress to be sure without any plugings. It’s working fine on the / (root) btw.
