Polylang easy to install. But then …

Indeed. Installing and activation is easy. But then you have to become aware how things work. Setup Wizard does its job without fuss. But then .. You should read the Getting Started documentation careful. A warning: Do not try installing Polylang on an existing website with a large number of pages and subpages if you don’t understand its ways. If you are starting a new website, it’s great. Switching languages on the website works perfect.

One minor problem, categories in blogs don’t function. I hope this will be solved somewhere in the next updates.
