It took me a long time to find a plugin for making WordPress Web sites multilingual that didn’t frustrate me, and after endless battles with Qtranslate en WPML, I’ve finally found one that so far has been reliable and relatively easy to use.
It’s free, not overly complicated, extensive and the author keeps the plugin up to date.
Additionally, a blog post at WerdsWords let me make a little change to this site that will send an email whenever a visitor visits a page that doesn’t exist (anymore). The visitor lands on a 404 page and that will trigger the sending of an email and I’ll be notified of the problem.
