Each purchase grants you access to the VFB Pro plugin support service, which covers help with setting up the latest version of the product and direction on how to use the latest version of the product as advertised. The support service does not cover help with theme or plugin customization beyond the advertised features (see examples of support vs customization below), nor does it cover help on sites that are heavily customized or in situations where the core plugin files have been modified.
Additionally, if a bug is discovered in code, we will do what we can, within reason, to repair it. However, we can offer no guarantee nor can we commit to a timeframe for the repair. All support is provided via our ticket system; there is no live chat, phone or direct email support available.
