Browsers: Chrome, Chrome Canary, Firefox, Firefox Beta, Yandex, Beta Yandex what ever Edge is in the most current insider's build.
My testing VMs use Debian, Fedora, Centos, Slack, FreeBSD, and Solaris 11.
Laptop is Mac about 3 versions back. Phone Android on a Samsung S9.
So it's kind of driving me nuts. When I get a chance I'll spin up a new droplet and replicate this build maybe it's something in the MySQL or PHP interactions.
The Garage Journal build is almost exactly the same as this one. Just MariaDB instead of MySQL and different data center and server.
