When you use Social integration from the Pro plugin, sometimes images may not load or display incorrectly. There may be several reasons for this.
Our plugin offloads images from social networks to your server and sometimes such requests may fail, because of limitations in API calls. For example, in Google Photos we have exactly 1 hour to download images.
We recommend you set up CRON jobs and let our script run every 2-5 minutes. See possible solutions here:
Blocked Downloads by Your Server
Since our plugin offloads images from social networks (from 3rd-party servers), your server may block these requests. Sometimes servers may disable
allow_url_fopen PHP directive, so you will need to enable it or ask your host support for help. You can find additional info in Google https://www.google.com/search?q=enable+allow_url_fopen
