i think i broke my web server..

i was doing some changes that my co worker told me i should do to make my server go faster, but im getting this error now:

Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

Unable to open logs


what do i do?
