Trying to add Google AdSense to a client website built with WordPress. Set everything up but when i try to use Ad Manager i receive the same error message; Oops. Something went wrong. Please try again.
The most likely reason is that you are using a WordPress cache plugin. If this is the case, please follow the plugin’s instructions to clear the cache and then try again.
I am only using a few plugins and cannot see how to empty any cache.
Help or Recommendation please.
