Thanks for the report. I’ve never used mod_userdir but a cursory glance at it makes me think it should not affect CI4 of your Apache Config and .htaccess are configured accordingly. My first guess on the “doubling” is that your baseUrl is not set correctly relative to the Apache directives. Try adjusting that in Config\App and if you are still having problems see if you can recreate the issue in a barebones AppStarter repo so it is easy to reproduce.
