url giving 404 error when adding page

Question

good afternoon guys, I have a huge "headache" here on the trampo, I’m trying to add page on a site here, but it’s not working: I have to add a url like this: /novapagina sem extensão, but in htacces file is like this, and I’m not getting it right:

Obs: each phtml file is inside a folder, and the url calls by the folder name and not the file name
