This option to modify the .httaccess is only recommended for the syntax /%post%/, If you want to configure another syntax you should do the redirects manually with a plugin like Redirection.
Chaguo hili ili kurekebisha na .httaccess ni tu ilipendekeza kwa ajili ya sintaksia ya /%Post%/, Kama unataka kusanidi sintaksia nyingine anapaswa kufanya maelekezo ya kwa mikono na plugin kama Welekeo mpya.
