How to read a WordPress plugin compatibility report

A compatibility report is only useful if your team knows how to read it under release pressure.

Start with the three questions

One Folt scan groups the results from all of its selected environment runs. Read that report in three passes:

1. Did it work at all? — pass/fail count across the matrix
2. What specifically broke? — exact combo, stack trace, file/line
3. What's the blast radius? — popularity-weighted impact estimate

If you only read the pass/fail headline, you will miss the prioritization layer.

Treat stack traces as reproduction steps

A good stack trace includes the PHP version, core release, theme, and co-installed plugins. That is your reproduction recipe — not “please send error logs.”

Use blast radius to order fixes

Two failures are not equal. Fix the combo estimated to hit millions of sites before the edge-case warning — unless you have a contractual reason not to.

Diff release-over-release

Attach reports to releases. When a new failure appears, the report narrows the investigation to changes since the previous accepted scan. When a failure disappears, you have evidence that the fix worked across the selected coverage — not just on your laptop.

Walk through the sample report with screenshots and matrix output, then use the release checklist to decide where the report belongs in your process.
