In that case, maybe i install back the SEO URL.. there after, i uninstall again.. might be the way i uninstall the SEO URL in a jump method..
It should be, reverse the process by editing back those files, there after i delete the 2 files includes/classes/seo.class.php
admin/includes/reset_seo_cache.php
OR
i delete the 2 files 1st, than i edit those files back to orginal..
Which is the correct way of uninstall?
