Guys, looks like ClassiPress localization code is not quite right.
I rely on Codestyling Localization plugin for WordPress to check, create and correct localization files and apparently yours isn't made properly.
The message I get is "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."
