Answer 1

It was indeed a chmod story I did one little (magento/) chmod -R 777 var/ and all was fixed

Answer 2

Make sure that system.log is chown'ed to the webserver user. Mine is www-data. It also is chmod 777. I've noticed that when your /magentoroot/var/log files do not exist or are not set up correctly, magento will write log files / cache files to /tmp.

Also, do not delete logfiles. Use sudo truncate -s0 logfilename.log

It clears them.

Answer 3

Check in your webserver's temp directory. If the application cannot write to ./var/log/, this is where it ends up.
