Hi @sietssoo,
Thank you for contacting us! If you have cleared the plugin’s cache and these posts are still appearing, the most common cause would be that they are still cached in one of the following areas:
-Browser / Local cache
-Site caching from a plugin or directly from your web host
-Database / Object /OP cache
Another possibility is that there could be a problem occurring in the database that is not allowing the plugin to clear its cache.
If you are still unable to update the feed with the information above, please reach out to us via our support form here and also include the System Info from the Help page of the plugin settings and we’ll be happy to investigate further.
Thanks!
Louis
