Hi there - Lindsey here from Support. Amazing! I'm glad to hear that :-)
It's possible there may have been a momentary caching issue with your WP-Admin that was causing this issue which, as you have correctly actioned, can be amended by simply clearing your site cache.
Should you have any other issues with your WP-Admin or access to the site, please let us know and we would be happy to revisit this with you.
Best,
Lindsey
