Hello, after Uninstall JoomSef 4 my urls listed with the term "style-2" and would not have to appear, I have reviewed all the uninstall and there is nothing to uninstall.

Example URL incorrect: aincat.com/style-2/alquiler
Example correct URL: aincat.com/alquiler

Thanks and best regards

Hello if JoomSEF is uninstalled or even just not active, then the URL is probably being formed by something else. Either by Joomla default router or other plugin with functionality simlar to JoomSEF.
