Trying to run the carp example on Debian this time. The machine is testing with is an i5 with 8Gb of RAM and a 320Gb HDD. I'm getting the following errors in the frontend.cache.log when I try to access a site. Which debug flags should I try? It looks to me like a permissions issue, but I'm not sure what to look for.
Cheers,
MarkJ
