I was successful in doing an upgrade on another web server in my multi-server setup and so got up the courage to do my dedicated master cp. After a successful update when I go to my http://ispconfig_server:8080 I get a blank screen In var/log/apache/access.log I get: 76.xxx.xx.xx - - [02/Nov/2015:21:50:57 -0600] "GET /:8080 HTTP/1.1" 403 516 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:41.0) Gecko/20100101 Firefox/41.0" 127.0.0.1 - - [02/Nov/2015:21:55:04 -0600] "GET /server-status?auto HTTP/1.1" 403 477 "-" "munin/2.0.25-1 (libwww-perl/6.08)" My kernel is the correct version and apache is 2.4. I did download and run the ispconfig update.php and did reconfigure permissions and services Getting desperate. Any ideas where to start troubleshooting this? THanks!
