Thunderbirds are go!
Finally! This site’s been down for like a month, because my host upgraded to the new version of php. I have no idea what went wrong. At first I assumed it was related to the database, because the site was still up. Only the content was gone, i.e. posts and pages.
I contacted One.com (the host) who have been somewhat helpful, although in the end I found a solution on my own. I was getting error related to plugins and / or various php-stuff. Even after I deleted all the plugins. It turns out there is a certain situation in which they don’t deactivate in the database. This post helped me, it’s on WordPress.org.
Anyway, it seems everything is back to normal. I have to reinstall all my plugins, which sucks, but better than losing all the content. One will be upgrading the server that my other site pcblog.dk is on next week. I really hope it goes better, I have years worth of content on that site!
The error was the following, for those interested (at least it was some of the time):
wp-includes/plugin.php on line 166
