[TYPO3-english] Problem with realUrl

[Roberto Torresani]

Hi all!
I have some problem with realurl 1.5.3. I install it on a typo3 4.2.6, on a
server where I have other typo3 with real url 1.x.x (they work).

I install real url with autoconfiguration, I have the file .htaccess, the
lines in typoscript.
If I access to home page, the link of menu are in speking format. When I
access to the page I receive the error:
"Reason: "test/" could not be found, closest page matching is"

I try to install and enable devLog and I have the line:
- Entering decodeSpURL
- RealURL powered decoding (TM) starting!

What could be the problem? What tests I could do to find it?

Thanks everyone.
Roberto
