I have downloaded the latest version of Polylang yesterday. My site has two languages - English and Bulgarian. Bulgarian is the default language. And there's a strange problem with all menus in the navigation - they are not displayed in the site. When a menu is selected from the Customize Theme screen, it shows up in the preview. But when I hit Save & Publish and open the home page, the menus are not there. When returning back to the Customize Theme screen, I can see that the navigation menus are actually not saved - the select boxes for choosing a menu are empty.
When Polylang is deactivated, adding a menu in the theme works fine.
I test with the Twenty Fourteen theme. The menu, which I use for testing is the simplest possible - it contains only one custom URL link.
The home page shows the latest posts.
The permalink settings are /%category%/%post_id%-%postname%
My Polylang setting are here:
I didn't have this issue with the previous version of Polylang.
Thank you in advance for your help.
