Comment 0 for bug 1194310

I setup squid and the Squid cachemanager by installing squid3 and squid-cgi.

The proxy works fine. FQDN is also reported correctly and resolves correctly.

However, after opening cachemgr.cgi in a webbrowser, I'm correctly greeted with a login screen, followed by a HTTP 500. HTTPD's error.log shows the following error.

Full crash report attached.
