I am trying to install the Google Sitemap Generator plugin but in the readme file it says the following:
Use your favorite FTP program to create two files in your WordPress directory (that's where the wp-config.php is) named sitemap.xml and sitemap.xml.gz and make them writable via CHMOD 666.
It also says making your whole blog directory writable is not recommended due to security reasons.
My question is, exactly how am I supposed to create a file called sitemap.xml and sitemap.xml.gz in Filezilla and then making them writable via CHMOD 666 ? Any type of input would be greatly appreciated as I am still pretty new to WordPress.
