#333 – Error diplayed if I switch language from english to italian. Help!

I installed route 66 free in my Joomla 3.9.2 site
After installation two errors are notified on top of all pages in backend and in frontend.

These are the two errors:
Notice: Undefined index: it-IT in /web/htdocs/www.mysite.ext/home/plugins/system/route66/lib/router.php on line 38
Notice: Undefined index: it-IT in /web/htdocs/www.mysite.ext/home/plugins/system/route66/lib/router.php on line 40

My site is in Italian language, code it-IT.
If I switch the backend language to english one of these errors desapear.
If I switch also the frontend language to english both errors desapear.

But I need the language of the site to be Italian!
Can you help me to solve this problem?

Thanks

Hi,

Please check that your site is set up correctly for multiple languages. You can use the "Multilanguage status" administrator module to see if everything is set up correctly.

The site is not multilanguage. And that's the problem?

Hi,

We have fixed this already for the next release. You can set the "Error reporting" to "Simple" under Joomla configuration in order to hide the message until the update is out.
Thank you for reporting this.
