Flow-Flow Social Media – Some Facebook images not showing
Hi, URLs of pics and videos are expiring on Instagram/Facebook API side for security purposes, so they can’t be stored forever. The plugin will try to refresh links for the last 20 posts or less depending on settings.
Also, you can rebuild the feed cache manually https://www.dropbox.com/s/vr8xi7dqpxhrm1h/chrome-2020-10-30-16-11-50-wo9h3kj3Av.png?dl=0. (IN FLOW-FLOW SETTINGS, GO TO FEED, MENU, REBUILD CACHE)
And also, you can consider our cloud service Boosts https://social-streams.com/boosts/. It can cache pictures via our CDN, so links will not expire.
