A blank page after uploading an AI-generated site is almost always one of a few specific, fixable problems: uploading source files instead of the built version, broken relative file paths, or a client-side routing issue. Here’s how to diagnose and fix each one.
This applies whether you’re hosting on Builderall, Netlify Drop, Vercel, or anywhere else — the causes are the same because they come from how the site was exported, not from any one host.
Cause 1: You uploaded source code instead of the built output
This is the most common cause, by far. If your AI tool (Lovable, v0, or Replit especially) generated a React, Vite, or other framework project, the raw source code is not a website — it’s the instructions for building one. Uploading the source folder directly, instead of the build or dist folder produced by running the build step, results in exactly this: a blank page, because there’s no actual HTML for the browser to render.
Fix: run the build step (commonly npm install && npm run build) and upload the contents of the resulting build or dist folder instead of the original source. See How to Host a Lovable, v0, or Replit Project on Builderall for the full walkthrough.
Cause 2: Broken relative paths for images, CSS, or JavaScript
Even with a correct build, sometimes a page’s references to its own assets (images, stylesheets, scripts) use paths that don’t resolve correctly once uploaded to a different location than where the tool originally expected the site to live.
Fix: open your browser’s developer console on the live page (right-click → Inspect → Console/Network tab) and look for 404 errors on specific files. If you see files failing to load, check whether the path in your HTML matches where that file actually is in your uploaded folder structure — this is usually a matter of adjusting a base path setting in your build tool before re-exporting.
Cause 3: Client-side routing breaks on direct navigation
If your site has multiple “pages” that are actually handled by JavaScript routing within a single-page app (common in React-based exports), the homepage might load fine, but navigating directly to another page’s URL — or refreshing while on it — shows a blank page or an error.
Fix: this is a static-hosting configuration issue common to single-page applications, not specific to any one host. Check your framework’s documentation for how it recommends configuring static exports for client-side routing (often involves a redirect rule so all paths serve the same base file, letting the JavaScript router take over from there).
Cause 4: JavaScript execution errors
If the page loads visually but key content or functionality is missing, check the browser console for JavaScript errors — sometimes a build introduces a reference to something that doesn’t exist in the static export (an environment variable, an API call expecting a server that isn’t there).
Fix: identify the specific error in the console, and check whether it relates to a feature that requires a server (in which case, see Builderall vs. Vercel for an AI-Generated Website — some features genuinely need server-side hosting, not a static host).
If you’re still stuck
Double-check you’re comparing the live upload against the actual build output, not the original AI tool’s live preview — previews sometimes run in an environment slightly different from a plain static file server, which can mask issues that only show up after export.
Once your site is actually live and working, the rest of your Builderall account — email automation, booking, chat, social proof, courses, and lead tracking — is already there and ready to connect. See Your AI Website Is Live. Now What? for that next step.
Frequently Asked Questions
Why does my site work in my AI tool’s preview but not after I upload it?
Previews sometimes run in an environment that’s more forgiving than a plain static file server — this is exactly why checking the actual build output (not just the preview) matters before uploading.
Do I need to know how to code to fix these issues?
Basic troubleshooting (checking the browser console for errors, confirming you uploaded the right folder) doesn’t require coding — but fixing a routing or path configuration issue may require adjusting a setting in your original AI tool or build configuration, which can take some trial and error if you’re not familiar with the framework.
Is this a Builderall-specific problem?
No — these are the same issues that come up hosting a static AI-generated site anywhere (Netlify Drop, GitHub Pages, Vercel without its automatic build pipeline, etc.). The causes are about how the site was exported, not which host you’re using.
What’s the fastest way to check what’s actually broken?
Open your browser’s developer tools (right-click → Inspect) and check the Console and Network tabs on the live page — most of these issues show up as a clear error message or a 404 on a specific file.
