I'm trying to log in in any user account and I just can't. When I enter the password of any admin account or even when I try to enter in the Guest account, a black screen appear showing:
* The apache2 instance did not start within 20 seconds. Please read the log files to discover problems.
*Starting Tomcat servlet engine tomcat7 [ OK ]
*Starting Red5 Server red5 [ OK ]
*Starting daemon monitor monit [ OK ]
After this black screen (which disappear in 1 second) it back to the log in screen. I can't read the log files (at least I don't know how), and can't open any user account or guest account. Anyone has an idea of how to solve this? (This is happening on ubuntu 14.04 64bits)
