All WordPress products contain bugs. If you stumble upon one, please report it using our Support forums on CodeCanyon or WordPress.org.

How to Choose WordPress Products
Themes often contain things like custom sliders, shortcodes, widgets, layout managers, content builders, portfolio functionality, etc. Be careful when choosing a theme like this. If you decide to switch themes at a later date you will lose all of the custom functionality you have come to rely upon.
Our advice is to always look for lightweight, lean WordPress themes and then add extra functionality via plugins. That way when you switch themes the functionality remains.
