Per:

http://www.sbarjatiya.com/notes_wiki/index.php/Configuring_squid_cache_manager

You should be using the userid root and the password you have configured for cachemgr_passwd in squid.conf.

Is that what you are doing?

You should not be specifying a port in the cachmgr login.

i.e. 127.0.0.1 might not be a "valid" host for cachemgr auth.  Try in the login to cachemgr cgi-bin to reference the systems LAN IP.

192.168.0.3
root
password

It can also vary and use the server's name.

The error you get when you follow the referenced link is likely because you duplicate entries.

Your issue with access deals with your definition of the webserver ACL which is in conflict.
Your rule is to allow all. You then within the cachemgr interface going to localhost, but the rule requires the source IP accessing cachemgr to be the webserver.

Either remove the webserver from the manager  entry
Http_access allow localhost manager webserver
Or change the ACL webserver src
To include your LAN, or you ..........
