Your problem is ports... My suggestion is change wamp server's port.
You check httpd.conf file.
-
#Listen 12.34.56.78:80
-
Listen 80
-
This paragraph in httpd.conf file. You will change 80 number with 90 or other number and restart wamp server... After when you want enter localhost, you will
http://localhost:90 (or other number)
Sorry for my bad english. I hope i did help you.
