When you post on Facebook and include a link to your brilliant new EvolutionX store you might get a gray box instead of an image from your website, like this:
Wow, that's disappointing. So you can call Mark Zuckerburg and ask him to clear the cache at Facebook or you can fix it yourself, here's how.
Test and Clear Facebook Cache of Links
The Facebook debugger has two great features. You can test your link and get the same broken result and you can clear the cache at Facebook. This is good because you can also retest after you clear the cache and see that it's fixed.
Testing Links at Facebook
Test your link at facebook https://developers.facebook.com/tools/debug/sharing/
Clearing Facebook Cache
Next you can clear the cache at Facebook using the Batch Invalidator.
Use the same link in the batch invalidator to clear the cache at Facebook before you retest https://developers.facebook.com/tools/debug/sharing/batch/
Retest Your Link
Retest using the link again using the debugger and you're all good 👍
