The Facebook live feed isn’t working for me yet. They told me I have to pay $150 for someone to look at it. I will probably be paying this today and they will be enabling fragment cache to get it working. I’ll let you know how they get it working either way.
Maybe I’ll wait for W3TC to fix the facebook issue and see if the solution involves fragment cache. If it does, perhaps you can recommend a solution for the categories. How does that sound?
