In Finnish, we have this lovely little word “murheenkryyni”. It’s originally an euphemism for body lice – you know, to avoid calling a nasty thing with its real name to avoid inviting it in – but has since taken a wider meaning of something that is a constant source of sorrow.
In Relevanssi, that is the auto-update, which broke again in 1.9. I thought I fixed it 1.9.2, but it turns out half of the fix didn’t quite make it to that release. Thus, 18.104.22.168, which should fix this for good. I’m very sorry it is such a struggle to get it right.
