@julian but the point is that I haven't modified any of those files. Most of the files were text files like for example: README.md, LICENSE, etc.
Why would I modify any of those?
Tweaked settings in admin control panel
Tried to update to 0.7.3 -> got errors
Actually I got help from Nodebbs IRC- channel on how to resolve these errors with git and I'm now running 0.7.3. but it was not easy, I've no experience with git and no idea why I have to deal with stuff like this when updating.
This is the manual how to update/upgrade from v0.5.0 to v0.6.1
git checkout c9228f14837fcf2903923ebca3d90a0d1517a713 (I don't now why v0.5.1 doesn't work in cli and csrf token error)
git checkout d341428ca1b88d56f7c7fe37d3e5e87d83bb0698 (v0.5.2 doesn`t work in cli too)
