The WordPress version that is used to create the town website was upgraded to version 4.1 today. It had previously been at the version 4.0.1.

There was one hiccup: no one could not log into the dashboard afterwards! The message “Did you take a wrong turn?” appeared instead. Sometimes a message about a redirect loop was displayed instead.

The solution was for one of the editors to log into the server where the program is running and change the permissions of files to “644” and the directories to “755” (which ironically limits ability of certain programs but means the system as a whole can then function). It is not known what the automatic upgrade process did not change these settings.
