WampServer

My wampserver just looks fine from June 2. I was in my wordpress dashboard and a few minutes later I just could not access it. I have not added any application to my PC.

I am not sure what is the cause of this issue. I have read other threads in this forum about port 80 and about skype. This is the last log of apache. I noticed unclean shutdowns and httpd pid overwritten. I am not a wamp expert and I need help on this.

Check your hosts file

C:\windows\system32\drivers\etc\hosts

it should have an entry
127.0.0.1 localhost

comment out this line if it exists
::1 localhost
#::1 localhost
