This is the common issue, you have changed the feature image of your project, uploaded it to your WordPress site click “save” everything seems to be ok but… for some reasons when you want to share your project on facebook the old facebook featured image is used… It can be a real mystery why is that?
The answer is the Facebook caching system. The elements can be stored on their server for months! The only solution is to force the Facebook system to clear the cache. To do that we need:
- go to https://developers.facebook.com/tools/debug/sharing/
- put the address of your main page
- click debug
- and then click scrape again button
If you don’t see any image this is usually because the featured image not meeting Facebook’s size requirements. The feature image should have at least 1200 x 630 pixels.
