Too many redirect

[gnolino]

Hi,
I' m using last version osclass with ssl protocol and pemalinks, if I write on the nav bar my site url, slash and a page that doesn't exist I'm redirect on 404 page.
I can write everything but not 1!!!
Example: "https://my_site.com/2"
I'm redirect to 404 page
But if I write:
"https://my_site.com/1",
I'm redirecting 19 times into a 302 loop and the browser say too many redirect, ect, etc...
I made a lot of test and I saw that is work well without permalinks.
I resolved it redirecting URI to onother page but may be someone  knows what is the problem.
Who knows?
