Hey guys, thanks for the update. I indeed use AdBlock, but, for the sake of testing ads on my site have deactivated it on my entire domain (and on some others I’d like to support).
That includes the admin section of WordPress, so actually I should have been able to see your plugin.
Anyway: It might be a good idea just mentioning that somewhere, to help other people who experience the same problem. I even googled how to uninstall the plugin and didn’t find that hint.
All the best!
