Main one: BugBot is a paid feature. You can’t add or enable it on repos on the free plan. You’ll need Pro to use it.
That said, the blank page is a bug on our side. Instead of a blank screen, you should’ve seen an upgrade prompt explaining that a paid plan is required. This is a known issue in the BugBot dashboard area, I’ve filed it separately.
Also, this doesn’t block Cursor itself the editor, Tab, Agent, etc. Only BugBot is unavailable. If the editor is also acting weird, let me know and we’ll dig into that separately.
