We migrated our site to a new server/url. Purchased a new license and installed it and all was fine. Today we suddenly got a “License Not Found or Invalid” message. Tried re-uploading the license. Looks like there is supposed to be an error message - red box with not text. Any ideas on what might be going on and how to fix?
