Greetings,
I have an otherwise-working Redmine 6.0.4 instance and I am trying to install a theme that is listed as being 6.x compatible. The theme can be loaded if placed in /themes but its css clearly doesn't load when it is selected. When I reviewed the instructions on the Themes wiki page, there is a note that in addition to the change in theme folder location, it is also necessary to serve /themes explicitly and an example for this is given for Apache. What is the example for the default puma server that Redmine uses?
How to use a theme with Redmine 6.0.4 and puma
