当挂上代理科学上网出现如下提示时：
Privoxy encountered an error while processing your request:
Could not load template file no-server-data or one of its included components.
Please contact your proxy administrator.
If you are the proxy administrator, please put the required file(s)in the (confdir)/templates directory. The location of the (confdir) directory is specified in the main Privoxy config file. (It’s typically the Privoxy install directory).
说明你代理服务器的端口已经被封了，这时登录你的服务器改变代理软件所用端口，重启代理程序就可以了。
