Hi wpauthority,
You are the very first user telling about such problem! Did you have a look into the plugin settings after activation? It is necessary for working perfectly!
I double checked it. It does not work. I tried it on freshly installed WP site, with all default themes and plugins. I wish it worked.
Which Wikipedia do you use as base URL? And, which Browser do you use?
Ok, I check this issue with a freshly installed WP site, and finally could reproduce the problem! Please review the settings and SAVE them (even if you did no changes). Afterwords everything should work fine!
