WordPress said: PCLZIP_ERR_BAD_FORMAT (-10)

I had an issue… I couldn’t upgrade my WordPress to 2.8.5 because of an error: ‘PCLZIP_ERR_BAD_FORMAT (-10)’. What is it and how to fix that problem?

WordPress on nginx + lighttpd + FastCGI + php

Sure, you can always install Apache. However… sometimes you can’t… for example: there could be some other web server installed on your port 80. There could be nginx for your python projects already installed (like in my case).
