Possible Causes:
Possible Cause #1 – The Free version of the plugin is still installed and activated.
You can quickly check this by going to your WordPress Dashboard > Plugins to see if you are still using the Free version called Smash Balloon Instagram Feed or Smash Balloon Social Post Feed, which does not display images. Instructions and guidance to set up the plugin can be found here.
Possible Cause #2 – The plugin’s setting has been set to not show “media”.
Check it by going to Facebook Feed > All Feeds > Edit > Posts > Edit Individual Elements > Photos/Videos. Ensure the box is checked and click Save.
Possible Cause #3 – The image(s) are being shared from a restricted Facebook account.
Go here for more information regarding “account restrictions”.
Possible Cause #4 – The “Site Accelerator” feature of the Jetpack plugin is enabled.
You can learn more about that feature here. Deactivating that feature in the plugin may resolve the issue. You can also check the above link for further troubleshooting steps.
Possible Cause #5 – The “Lazy Load” feature of the Jetpack plugin is enabled.
Lazy Load plugins can interfere with the way our plugin displays images in the feed. If you’re using the Jetpack plugin then you can disable Lazy Loading in the following location: Navigate to Jetpack > Settings > Performance. Scroll to the Performance and Speed section. Click the toggle to activate or deactivate Lazy loading for images.
Possible Cause #6 – An add-on or extension you have installed in your web browser (often Firefox) is blocking the photos being loaded from Facebook.
Try checking to see whether you have any add-ons or extensions installed in your browser and if so, try disabling them to see whether that solves the problem.
You can also ensure that you do not have Optimize Images disabled in the plugin under Facebook Feed > Settings > Advanced > Optimize Images. With this enabled the plugin will display locally resized images from your server, solving most issues with Ad & Privacy blocking extensions.
Possible Cause #7 – You are browsing using Firefox’s “Private Browsing” mode and have “Tracking Protection” enabled in the settings, and/or the Firefox Facebook Container feature is blocking content from Facebook.
You may need to disable this as it blocks some Facebook images. If you want Firefox to display content from Facebook, you will also need to add the page to the Facebook Container feature in the top right of the browser window.
You can also ensure that you do not have Optimize Images disabled in the plugin under Facebook Feed > Settings > Advanced > Optimize Images. With this enabled the plugin will display locally resized images from your server, solving most issues with Ad & Privacy blocking extensions.
