MijoSEF does not work with JoomFish

Go to Extensions -> Plugins and check that the System - Jfrouter plugin is disabled.

If disabling this plugin causes the following error:

mod_jflanguageselection.php on line 75

Then apply the following steps:

OPEN

modules/mod_jflanguageselection/helper.php

FIND

$menu->_items = JFModuleHTML::getJFMenu($language->code, true);

REPLACE

// $menu->_items = JFModuleHTML::getJFMenu($language->code, true);
