can not access to virtual files/directories

I just update from git and build on debian gnu/linux

I get not found errors when access to my libraries via http://host/files/xxxxxx

notice the "404 .html" name (space before dot)

I think that is related to ARS because, this dir have free access and work:

https://bbs.docksud.com.ar/files/Zudaka/Zudaka.Info.Pack/

but, this other dir, need to have access to "LEVEL 1" and do not work:

https://bbs.docksud.com.ar/files/AmigaNet/
