An old client just contacted me about not being able to log into their website. I looked and saw this: https://screenshots.firefox.com/X6DtduB4Oqrd8ZUe/brightstoneathens.com

I setup this site for them when I had an unlimited license - are those no longer valid?

P.S. the "developer mode" link in the screenshot goes to a 404 @ https://docs.statamic.com/knowledge-base/developer-mode
