I have this error when trying to browse php files locally
[Fri Apr 13 19:16:40 2012] [alert] [client 127.0.0.1] C:/AppServ/www/hr-website/.htaccess: Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration, referer: http://127.0.0.1/
or defined by a module not included in the server configuration
Check to make sure you have mod_rewrite enabled.
LoadModule rewrite_module modules/mod_rewrite.so line is missing from the httpd.conf file entirely, just add it.
