It does work.
if you are getting the error about
just click save and ignore the error. It seems that if on the options page you don't have the correct XenForo directory it throws an error. After the first error you will get a second error, again save and ignore it.
Then go back to the options screen and correct the XenForo directory.
If you still can't get it to load then go into the file xenlastposts.php line 100 and change
PHP:
$dbconfig ='.'.$xendirectory."library/config.php";
to the following; using your full directory path, something like this....
PHP:
$dbconfig = '/your/fulldirectorypath/public_html/beta/xf/library/config.php';
$dbconfig = '/home/eipsoftware/public_html/beta/xf/library/config.php';
Hope this helps.
