“Cheatin’ huh” when I try to use Translate Press

I have been using Translate Press for months now. All of a sudden, I wanted to change a translation and when I click ” Translate site” I am brought to a page that says ” Cheatin’ huh?”

I have tried deactivating all plugins and none of them seem to be the issue. I have also tried deleting and reinstalling the plugin.

My site looks a bit ridiculous at the moment as what is meant to be the French page is in both French and English since I was unable to go back and finish translating !

Many thanks for any help,
Stephanie
