[muhsing]

Hi everybody.
I have a one question for facebook share.
When i like to share category, have some problem. Pictures is good but category title and description show wrong.
In the end i find where is the problem.
Category id and article id have a conflict. In example when i like to share some category, showing the article title who has a same id number with category id and article id number.
And my question is how can i fix this problem. Thanx..
