Menu Access App not working in Joomla 3.4
From Joomla 3.4 Menu access app will not work with multilingual, due to major changes in J3.4 core. It's not possible to override menus (Show/Hide Menu functionality) using Menu-Access plugin.
If your site is not multilingual then Please disable* Language filter* Plugin if enabled .
*In PayPlans 3.1 and 3.2 series *
We got one more issue and already fixed , but it has not been released. We would be releasing it soon.
