I’m learning the Zend Framework with the help of the quick start tutorial. I received a ‘500 internal server error’ when trying to access /guestbook. A look in the Apache log file (/private/var/log/apache2/error_log or via Console.app) reveals that mod_rewrite is exceeding 10 redirects. The solution is to edit /quickStartRoot/public/.htaccess file so that the rewrite is an absolute path, ie the last line should be: RewriteRule ^.*$ /index.php [NC,L]
