The JPromoter standard com_content XML with counting Itemids, they are included as menu names in SEF, also it is processes with LOWER function so sefs will not be case sensetive all letter will be low cased.

To use it simply overwrite old com_content XML into /administrator/components/com_jp/sef_configs and clear/delete all old SEFs for only content.

Note: we recommend did delete SEF if it possible, but in this case you will lost all custom metategs, but if you don't want lost them use clear SEF.
