duh, I always forget my host uses php4 by default.
I just just add this to my .htaccess file
AddHandler x-mapp-php5 .php

Blank page without error 500 can happen if your zip file or upload itself is corrupted. Try re-uploading using filezilla in binary mode. also try deactivate other plugins and activate WLM first. then activate other needed plugins.
