Facebook for Woocommerce and W3TC

Hi,
I’m using Facebook for Woocommerce plugin on my site and when I try to modify a product through WP admin, the product’s modification link is not working:
“This page isn’t working
https://www.ihome.am is currently unable to handle this request.
HTTP ERROR 500”

Then I received an email from WP saying that there is a fatal error on my site (with the link to product modification page) caused by Facebook for Woocommerce.

Once I disable the Facebook for Woocommerce plugin, product modification works well.

Another info that may be interesting also is that the problem gets fixed once I disable W3TC plugin. So when I have these 2 plugins enabled, the product modification page becomes unaccessible. I have to disable one of them… but since WP is sending a fatal error caused by Facebool for Woocommerce plugin, I suspect that the problem comes from that plugin and not from W3TC.

Anyone knows how to resolve the issue ?
Thanks
Semyon
