WP Blog LinkedIn App does not work anymore. What can I do?

HI everyone!

I have been using LinkedIn for years and over the past few months I have used the WP LinkedIn app that allow(ed) me to show my WP blog in my LinkedIn profile.

All of a sudden the content of the blog is not showing up anymore. I have tried to delete the app and relink it to my blog but no luck. LinkedIn is unwilling to help as they say it is not their business and they do not manage the WP app (not very good attitude!!). Do you know what could I do to get the content of my blog back into my linked in profile (I am not very techie so I will be unable to understand html & co)

Many thanks for your help ??
