Installed, uninstalled as I thought it was having conflicts.
Went to phpmyadmin and dropped all records from wp-options table with "gsom" in them and reinstalled plugin. Now I get no "subscribe" button, or options for it in the admin panel.
I realize that I may have screwed something up dropping records from the db. I am pretty confident doing that in most cases. But wouldn't a fresh install of plugin create fresh records again in wp-options table? Am I missing something?
Thanks!
