I downloaded and installed the better user shortcodes plugin and created a registration page on a site I have been working on. On my development server the registration works perfectly (The registration involves entering an email, username, password and password confirmation). However when i put the registration facility onto the live site, when you attempt to register all I get is an Internal Zend error which says something about missing class information in the the classes/config.php file within the plugin folder. This error message is then displayed to anyone who accesses the site (any page) for a short period of time before it returns to normal which is not good for a live site.
Does anyone know what could be causing this?
