No one is looking for "a helping hand".
Hundreds of users are experiencing the same BUG in W3TC. We have all tried to get the developers to address this BUG. We are not looking for help in setting up the plugin, we are not looking for "a helping hand with the free features." We are looking for the developers to FIX A BUG.
If I pay for software and it has a bug, the developers must fix that bug. Period.
The good news is that (perhaps due to this bad publicity) one of the W3TC engineers has contacted me about the bug. I've given him access to my site so perhaps we'll see a fix for this bug soon. Since it's clearly affecting hundreds of users (do a Google search and you'll see) let's hope they find a fix!
