Hi @tonyghagan,
It sounds like you’ve removed your STYLE component. Restore your OJS 3.0.2 database from backup, and before running the upgrade, login as Journal Manager. In Settings > Workflow > Components, create a new component with name “HTML Stylesheet”. Check “Mark files of this type as dependent files” and enter STYLE in the “Key” field.
Then, with this fix applied to your OJS 3.0.2 database, you can try the upgrade process again.
