Getting this message: Uh oh, we couldn’t check if this license was valid. Details.
I click on Details and a dialog box pops up with no message in it.
I had some kind of issue with the site where WP couldn’t find the DB so I reinstalled it and everything seems to be fine. I then activated X theme and tried to validate, but it failed.
If the site doesn’t validate with the key still. Please provide us wp-login credentials and the API key on a private reply, so we can take a closer look.
