Custom Rendering functions Error

I found the errors in wcff-builder.php about line 1356 & 1357, which is designed to check for the custom wrapper actions; the actual commend is “do_action” not the typo as “do_filter”. Also the following 2nd parameter you put is $_meta, well, I think it’s best for end-users to decide how to manipulate the rendering result, so I would recommend you to change the responding content in online document.
