I've updated the credentials. By the way, since tonight, the news page (blog layout) was no longer works. It produces a 'Class 'JA WallHelper" error'.
I did a search for it and found someone saying something about this error being caused by the JA Pager plugin, so I had a look. I discovered that this plugin was disabled and turned it back on. Lucky, the news page was working after that again. Really weird.
