Hello and Thank you for the great tool,
After upgrade to WW 2.17 all requests for js/css files in folder pg_files return with error code 404.
Folder permissions allow reading.
I've added this line to apache configuration file : push @Alias, [ "/pg_files" => "$pg_dir/htdocs" ];
All files requested exist in /opt/webwork/pg/htdocs/js/apps/ folder.
