I also receive a 500 error when attempting to use this plug in.
I followed the work around instructions offered above but get the same error regardless.
I attempted to enable DEV_MODE in order to generate a specific error to report but when I did that my site didn't load at all.
I replaced the config.php file with the back up one I saved before hand, so my site loads again, however I am back to square one.
means i posted something on group
can i or some one comment on that single thread like feeds in main page..
