Troubleshooting

Quick fixes for the issues you’re most likely to hit — missing tables, a greyed-out preset, a slow chart, or an embed that won’t render.

Step by step

1A new table isn’t in the builder? Settings → Refresh schema (introspection is cached for an hour), and check Schema mode isn’t restricting it.
2A preset’s Install button is greyed out? Its required plugin isn’t active — the card shows which one.
3A chart is slow? Lower Max rows, add filters, or enable Materialization (Pro) for heavy aggregates.
4An embed won’t load? Confirm the token isn’t expired or revoked, and that your host isn’t sending a conflicting X-Frame-Options header.
5A SQL query is rejected? It must be a single read-only SELECT / WITH … SELECT — remove writes, multi-statements, or forbidden functions.

REST returns HTML instead of JSON

A PHP notice leaking into a REST response usually means the schema is stale after an update. Glimpse BI self-migrates on load, but if you see it, deactivate/reactivate once to force the migration, then retry.

Still stuck?

Enable WP_DEBUG_LOG to capture details, note the chart definition and the exact error, and reach out via your glimpsebi.com account. Your data never leaves your server, so logs stay with you.
