Hi,
i recently installed code styler translation plugin http://wordpress.org/extend/plugins/codestyling-localization/
which was recommended by woocommerce support
it reports this issue with contact form 7.....
Loading Issue: Author is using load_textdomain instead of load_plugin_textdomain function. This may break behavior of WordPress, because some filters and actions won't be executed anymore. Please contact the Author about that.
