I can't restart Apache: if I try to start it, the error is this:
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down AH00015: Unable to open logs Action 'start' failed. The Apache error log may have more information.
If I try to stop it (even if it's not running), the error is this:
There are processes named 'apache2' running which do not match your pid file which are left untouched in the name of safety, Please review the situation by hand.
The problem is that I can't kill these processes; I tried with
sudo kill -9 #PID but nothing happens. I check the pid file of Apache2 in run/apache2 but there is no files.
How can I solve?
