Hey deniseking2506,
To answer your question… the ellipsis should expand the rest of the article/post text if you click on it. If this is not working properly for you can I have you submit your issue on our support page here. We would be happy to look into this further for you.
When submitting your support request please include your plugin’s System Info as it will help us better determine what the underlying issue might be.
To get your plugin’s System Info go to:
WordPress DashBoard – Facebook Feed – Settings – Support (tabbed page).
Select all text in the “System Info” by clicking in the box, copy and then paste the ‘System Info’ into your reply.
Also provide the shortcode you are currently using and the link to the specific site page where you have the plugin’s feed installed. I will wait for your response.
