Today I’ve updated WordPress from 3.8.1 to 4.1.1. This was sort of overdue for some time and I’m not sure where I found the bravery today. After 30 minutes of sweat and fear it seems everything went well (otherwise you would have difficulties to read this).
For those of you who are in a similar situation I recommend to follow the Manual Update Section of https://codex.wordpress.org/Updating_WordPress since an Auomatic Update failed in my case.
For the main content of this site you still need to go here.
