 * Hi [@toddbenton](https://wordpress.org/support/users/toddbenton/),
 * Thanks for reporting this!
 * We encountered an unexpected server issue on Tuesday evening which knocked out
   3 of our websites and caused those errors to temporarily appear in some users’
   dashboards.
 * Fortunately our developers were able to resolve the problem within the hour, 
   so you shouldn’t be seeing any warnings like that anymore. If you are, please
   [open a support ticket](https://formidableforms.com/new-topic/) and we will be
   happy to assist you.
