Joomla Free extensions

Hello,

I have some trouble loading Facebook box. In admin I can change language from English to French, but on page FB is in English. And I got this error: Strict Standards: Non-static method modJoFacebooklikebox::getLikebox() should not be called statically in /home/.../public_html/cliniquedentour.fr/modules/mod_jo_facebooklikebox/mod_jo_facebooklikebox.php on line 16.
I try Google but nothing...My Joomla was 3.3.3, I update to 3.4.8 thinking the problem solve, but not.
I need help please.

Thank you.

Hello Sorin
Please help me find and open file: modules/mod_jo_facebooklikebox/mod_jo_facebooklikebox.php and go to line 16 and added @ before this line

$content = @modJoFacebooklikebox::getLikebox($params);

Best regards
Bach Pham
