Sorry for late reply to this,
It seems like the Facebook token expired, can you provide us with your Joomla backend, Facebook access, and FTP access so we can help you check on this? Please advise.
I have included all the information in the Site Details below. Please be careful - I do not want the blog posts to go to my personal timeline. I want them to go to the company page for my client as status updates on that page (URL provided in Site Details)
