Hi Steve,
Just updated that I have fixed and can use both All in one SEO and W3TC.
I found it was the W3TC setting, and mainly because the minify.
Just simply add the “Rejected user agents” in all setting of W3TC:
facebookexternalhit
FacebookExternalHit/1.1
FacebookExternalHit/1.0
It works now. Thanks anyway.
