Today I received several of these messages from my hosting service. I can not find an error as the license says it is active. I have set up a subdomain for a test site and had my whole site copied to it (CBSubs says it allows a test site) just two days ago. Could that cause an issue?
On site ******* there is a paid subscriptions license message:
License server could not be reached. Please check that you have Internet connection (connectivity, firewall settings) or try again in half hour. Error:
Please log into administrator area and check the plugin settings.
Thanks
