Uh oh, we couldn't check if this license was valid. Details... FIX THIS PLEASE

I had xtheme on a website which I cloned, I purchased a new license and now it wont let me update cornerstone without validation.

Every time I enter my code I get the “Uh oh, we couldn’t check if this license was valid. Details.” message. If i click on “Details” it just goes to a blank screen.

Please help me figure this out

Hi there,

This seems to be a problem of connection to our servers to be able to check for the license validity. Most probably it is the restriction of the cUrl access to our servers by your hosting service provider.

Kindly contact your hosting service provider and give them the link below to follow up:

Thank you.
