Front-end doesn't use Italian language

After the last update in front end the italian language is not set on event booking

Before update everithing was ok and I didn't any change.
I have checked the translation in back end and Italian Language is ok, the language is set. I tryied to purge urls and fix database schema but nothing happen
where should i check?

Maybe the language file was broken for some reasons. Could you please submit a support ticket sending us super admin account of your site so that I can ask my developer to check it?

ticket sent.
Thank you very much for your support

Just for information, the issue happens because you are using special character " in the language item and it makes the language file broken

In the last release, we improved code to handle that. Now the language file won't be broken anymore event if you use that double quote character
