Hey @ashbryant,
we just issued an update that fixes the problem.
If you can’t login to your WordPress Dashboard, you have to connect to your FTP server and deactivate the plugin from there.
Just connect to your FTP server (If you don’t know how to do that, check this article.), navigate to the “wp-content/plugins/” folder and rename the “viral-coming-soon” to something different like for example “viral-coming-soon-xyz”.
This will cause WordPress to deactivate the plugin, so you can login again into your WordPress Dashboard.
Once that is done, please update the Plugin Files within your WordPress Dashboard to the latest version (1.1.1) and everything should work again as before without problems.
If you need assistance following these steps or want us to do them for you, just send us a quick email to support [at] growtheme [dot] com
