I love this plugin.
I noticed that when I have this plugin installed along side of another plugin called sCategoryPermalinks.
I have found that this line in sCategoryPermalinks code affects FEE negatively when saving a post edit:
add_action('transition_post_status', array(&$sCategoryPermalink, 'savePost'), -1000, 3);
With this plugin active, the "Save" button does not do as it should. The edits actually get saved to the DB, but the section being edited just turns grey and the spinner stays visible permanently.
If i comment out the line above, the FEE plugin works perfectly.
Does anyone know why that line is causing the problem with the FEE plugin?
