Prebuild, Cache & Deleting

Prebuild is the publish button for the whole storefront. It takes your active presets plus the latest synced data and bakes static pages that load instantly for shoppers. Almost everything you do in the Agentic Admin only becomes visible to customers after a prebuild.

Running a prebuild

1. Make and save/activate your changes (preset, page, style, theme) and run any needed syncs.

2. Open the Prebuild action and start it. It bakes the affected pages; larger stores take longer.

3. When it finishes, the Pages Prebuilt count on the Dashboard updates.

4. Open View Storefront to confirm the result.

What needs a prebuild?

Anything that changes appearance or content: activating a structural preset, publishing a page, applying a style, saving a theme, or syncing new data. When in doubt, prebuild.

Clearing the cache

If you’ve prebuilt but the storefront still serves an old version, the cache is holding the previous page. Clear it so the fresh build is served.

1. Use the Clear Cache action in the Agentic Admin (or your hosting/CDN cache purge if your store sits behind a CDN).

2. Reload the storefront with a hard refresh (Ctrl/Cmd + Shift + R) to bypass your browser’s cache too.

Three caches can hide a change

1. The prebuilt page (fixed by a Prebuild), 2. the server/CDN cache (fixed by Clear Cache / CDN purge), and 3. your browser cache (fixed by a hard refresh). If a change is stubborn, work through all three in that order.

Deleting prebuilt pages / starting clean

To remove baked pages — for example to force a completely fresh rebuild — use the delete / clear prebuilt action, then run a new Prebuild. This is useful when:

• You removed products or pages in Magento and want the stale baked pages gone.
• A build looks wrong and you want to bake it again from scratch.

Caution

Deleting prebuilt pages takes them off the live store until you Prebuild again. On a production store, delete-then-prebuild in a quiet period, or prebuild first and only delete what’s genuinely stale.

When a change isn’t showing

This is the most common question. Work down it in order; one of these is nearly always the cause:

1. Did you save / publish / activate the change in the admin? (A draft isn’t live.)

2. Did you run the right sync? Catalogue change → Sync Products; CMS change → Sync CMS.

3. Did you Prebuild after the change? This is the usual culprit.

4. Did you Clear Cache (and CDN purge if you use one)?

5. Hard-refresh your browser to rule out browser cache.

6. Still wrong? Check the source in Magento is correct, saved, enabled and visible.
