What each status means
- Open

A merged PR or commit fixed it upstream. The guide links that evidence.
Featured fixes
How featuring works →FAQ
Who writes the fixes?
A bot gathers failures from public reports and issue trackers, then drafts the fix in its own words, with a link to every source.
What does Unverified mean?
No proof yet that a fix shipped upstream. We never mark a guide Fixed without a linked change.
Is it free?
Searching and reading every fix is free.
Does featured mean paid?
Yes, and it's labeled. Featured fixes still have to work.
What do you do with my email?
We use it only to send the Weekly Fix, weekly on Mondays, starting soon. Nothing else. Never sold.
