Debug mode on but no logs? Ensure WordPress logging is configured (e.g. WP_DEBUG_LOG) and the log file path is writable. Use Download in Debug Log Management to confirm entries are being written. Check file permissions on the server if logs still don't appear.
Performance toggle unavailable? Convert new uploads to WebP shows as Unavailable when the server's image library (GD/Imagick) cannot encode WebP. Upload tweaks only apply to new uploads. Run Rebuild All Thumbnails to apply size changes to existing media.
Labs feature broke something? Disable the Labs feature in Settings → Fleek Labs and save. If the issue persists, use Clear All Cache in Debug Settings and reload. Report bugs so the team can improve the feature.
Safe for production? Debug mode and verbose logging can expose sensitive data. Use debug on staging or temporarily on production. Turn it off when not troubleshooting. Labs features are experimental, so enable them only if you accept possible instability. Rebuilding all thumbnails is safe but slow on large libraries and temporarily uses extra disk space.

In practice
Performance Center — debug logs, performance options, Labs issues, production safety. On this page, Performance Center: Tips and troubleshooting is covered in detail: what it looks like in the admin, the exact controls it exposes, and how it behaves when you use it day to day. The sections above walk through Quick reference in order, so you can skim headings and jump straight to the part you need. Because performance center: tips and troubleshooting is part of Debug & Performance tools — request diagnostics, cache controls, and Fleek Labs experiments built into the admin — the settings you touch here interact with the rest of the feature; when in doubt, open the feature overview and follow the docs in order.
