I encounter an issue with Webmin System Information page, which is loading forever but nothing shows on page. In miniserv.log I get alot of the following errors:
Use of uninitialized value in string eq at /usr/share/webmin/blue-theme/left.cgi line 157.

I've also changed the theme, and all do the same.
The only change on the server(Debian 7) was upgrading PHP from 5.4 to 5.5.29-1~dotdeb+7.1. Everything else is working fine on the server except system information.
Those are just perl warnings, so are unlikely to be the cause of the slow loading.
Does the page ever complete loading, for example if you want for 5 minutes?
Solved the issue, thanks for the hint.
I had an iptables drop of .cgi requests, as I've encountered many attacks on inexistent cgi paths.
