Hmm. When I try to "Like" your page, the proper title and description is shown. Additionally, when I run it through the
Facebook URL Debug
tool, the data appears correctly there.
My only guess is that it's an issue with your database character set/encoding/collation. As of JFBConnect v5.2, we began setting the character set for our tables to UTF-8. However, for installations before that (even if you updated later), the default character set for your table would have been used.
Can you use PHPMyAdmin or contact your hosting provider to update the following table to use UTF-8 encoding/character sets:
xyz_jfbconnect_request
After you make the change, make sure your Request is still configured properly and try again. If the problem is simply that the Request information isn't being stored or transmitted to Facebook as the correct format, that change should fix things.
I hope that helps,
Alex
