I have just bought X today from Themeforest. I installed it on a live website to test it, and I keep getting this error “We’ve checked the code, but it doesn’t appear to be an Cornerstone purchase code or Themeco license. Please double check the code and try again.”
What’s more, when logged in to wp-admin I am getting a server 500 error on the front page despite not having the X theme active. The X license is validated but not Cornerstone. I am not in an infinite loop of getting these messages everywhere in wp-admin.
