 * Installed version 3.0 and pages where I have reviews will not show the whole 
   page.
    In my error_log file I get this:

 * That issue will be fixed in version 3.1 which brings numerous improvements to
   the caching mechanism as well as WooDiscuz support.
 * I hope you can bear with the warnings for ~20 hours more 🙂
