Your site permalinks doesn’t seem to work with pretty links ? ==> mod_rewrite doesn’t work !

Solution: make sure mod_rewite.so loaded on your httpd.conf and AllowOverride must set to all !

LoadModule rewrite_module modules/mod_rewrite.so

Search in /etc/httpd/conf/httpd.conf

<Directory />
***********
AllowOverride None
***********
</Directory>

and change AllowOverride line :

<Directory />
***********
AllowOverride All
***********
</Directory>

AllowOverride directive

Syntax: AllowOverride All|None|directive-type [directive-type] …
Default: AllowOverride All
Context: directory
Status: core

When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information.

When this directive is set to None, then .htaccess files are completely ignored. In this case, the server will not even attempt to read .htaccess files in the filesystem.

When this directive is set to All, then any directive which has the .htaccess Context is allowed in .htaccess files.

Note: AllowOverride is only valid in sections, not in or sections, as implied by the Context section above.
