I’m having the same issue as martisque. I uninstalled and reinstalled and now get the error “The plugin does not have a valid header”
Plug-in version 0.5.3
PHP version 5.3.10
Wordpress version 4.6.1
I have not changed my theme or any other plugins. Also I hadn’t tried using the plugin since the wordpress update.
Thank you for any help you can offer. I love this plug-in ….please help!
