I am using 3.8.1 and it works just fine…
This plugin was updated this month but I’m still getting a blank white page whenever I activate this plugin which I really like. Now I have to use Simple 301 Redirect plugin until the author fixes this problem.
I’m using the latest WordPress 3.9.1
OK, I went into the database and deleted a record that I suspect was the cause of the blank white page problem and now the plugin works. However, links are not opening in a new window as set by WP External Links plugin.
The external links work on another site with this plugin but not this site which uses a different theme.
