We have a website that is currently on X 6.2.2 and Cornerstone 3.5.4. We have been unable to update Cornerstone in quite some time as it says the X license is invalid. We have removed the X license and added it back multiple times but Cornerstone still says it is invalid. We did a few manual updates of Cornerstone to get around this but it never changes the license validity issue. When we did the manual update we completely deleted the cornerstone plugin folder and replaced it with the newer version.
Recently, we noticed that X is not updating either. It shows 6.2.2 as the latest version under the validation settings. If you click check now, is says nothing to report. Please advise on how to fix this. The fixes we found in the forums so far have not fixed the issue.
