How to Rewrite WordPress Mods

1. Ask your Web host to enable mod_rewrite on your server so you can create WordPress permalinks. Depending on your host, you may need to submit a ticket to request this server change. The Apache module mod_rewrite may come enabled by default on your server. If it isn't enabled before starting, you won't damage anything on your WordPress installation or your server. The permalinks simply will not change.
2. Open your FTP software and connect to your Web server. Navigate to the base WordPress installation folder. Look for a file named '.htaccess.' If you don't see a file with this name, create a blank TXT file and name it .htaccess. Upload the file to your WordPress base directory. Right-click the file and click 'Permissions.' Type '777' for the file permissions.

3. Log in to your WordPress administration panel. Click 'Settings.' Click 'Permalinks.'
4. Click one of the default permalink structures or click 'Custom' to choose your own. You can use parameters such as %postname%, %tag% and %author% in this field. Separate each parameter with a backslash.
5. Click 'Save' to save these settings. WordPress writes the permalink structure to your .htaccess file.
