Got 2 reports of a 500 error on OpenAdmin > Users today on a freshly installed OpenPanel 1.6.3 on Ubuntu24:
'NoneType' object has no attribute 'cursor'
It will take some time to troubleshoot the root cause, but for now if you experience this, simply deleting the volume and restarting mysql to re-initialize resolves it:
cd /root && docker compose down --volumes && docker compose up -d openpanel_mysql
NOTE: ONLY RUN THIS ON FRESH INSTALLS AS IT WILL DELETE ALL USERS,PLANS,DOMAINS,WEBSITES..
