Can't add properties in French at front-end

Hi Everyone,
Some customers asked us that they can't add properties at front-end in French language and there is the Javascript issue at the "add property" form. The problem is why at different language, we can add properties normally except at French language. And here is the reason, in "Add property" form, OS Property uses several Javascript functions. In one of them, there is the command: ALERT, and if we are in French language (Joomla front-end), we have this code line
alert('Type de fichier n'est pas autorisé. Autoriser fichier');
If you know a bit about Javascript, you will see the problem. In above code line, we have the error with ' in the translated sentence. "Type de fichier n'est pas autorisé. Autoriser fichier"
To solve this issue, please go to Back-end > OS Property > Translation tool > Filter: French, Front-end, keyword "OS_ALLOW_FILE" and remove ' in the translated content.
The issue will be solved
Good luck
Dam
