I made a site live and my X theme says my license of X is not validated. The CSS of the X dashboard is all screwed up now, with very large icons and unformatted content. On the 'manage license' page, the information is entered correctly (staging and production sites). When I try to validate the license, my WP dashboard is just a blank white page. I have various other licenses on this same server, so there shouldn't be an underlying server issue.
I am unable to update the theme and cornerstone.
I would be happy to provide an admin login so you can log in and try to correct my issue. Thanks.
