Hello, could someone help me?

I have problems when I click the ad, after a search. The moment will load the ad page, it is a trying time, but carries not generating an error in the browser. Error: "This web page has a redirect loop."

In Apache log file have the following several lines like this:
127.0.0.1 - - [24 / Mar / 2015: 21: 08: 15 -0300] "GET /flynax/autos/chevrolet/impala/imapala-gt-3.0-new-r-21.000.00-used-2.html HTTP / 1.1 "301 -

All the site remaining functions normally. I've looked the .htaccess file, but found nothing that would cause this problem, although I think that that's where the problem is... My site is hosted on localhost in "flynax/index.php".

The rewrite_module module is enabled on the server.

Thank U,
