Thanks for updating the thread.
I checked the licence manager and can see that you have two X Theme licence. I checked both the websites that's listed and I would like to share few things which I think are causing the issue.
- Website 1 (URL in secure note): Over here I see that you are using X Theme 6.3.8 and Cornerstone 3.5.4. If you are trying to validate this website then I suggest you to first update X Theme and Cornerstone to latest version i.e X Theme 6.5.6 and Cornerstone 3.5.5. You will have to update the same manually. Please refer our theme update guide and in that scroll down to manual update section.
- Website 2 (URL in secure note): Over here also I see that you are using fairly old version of Cornerstone 1.3.0. Please update Cornerstone to latest version 3.5.5 manually.
Before validating it's vital to use latest version of X Theme and Cornerstone to avoid any compatibility issues. So depending upon which website you are trying to validate, please manually update X Theme and Cornerstone and then try to validate.
