The site is completely functional and you can read and access everything through the menus above – but navigation via the links, categories, tags and so on, is currently non-functional and being repaired. That’s a lot of work and will take several weeks, even a month or two. When this sign disappears, it will all be fixed. Sorry about the inconvenience.
NB: All FB “likes” are gone. If you liked a post before and happen across it again, do me a favour and like it again. It does nothing except flip a counter here and won’t redirect you anywhere – but it does tell me something about the popularity of a post. Thanks!
