I have been using Grafana OSS on my Desktop Linux connected to MySQL DB for the past few months. Then there was this issue where I could not log into the dashboard, so I updated the Grafana version and did a server reboot and was able to log in. But when I open my dashboard, they seems to be empty without the graphs. I tried to check my the SQL scripts and settings which all remained the same. Previously I used the “Transform” “Convert data type” feature to display the data but now the option is missing. Thanks.
