If you spend more than 5 minutes debugging a single issue, consider describing the problem to JustCopy.ai and letting it fix the code. AI can often solve in seconds what takes humans minutes to debug. Remember: JustCopy.ai creates complete websites in under 2 minutes - sometimes regenerating is faster than fixing.
Layout issues are the most visible problems in AI-generated websites. Here is how to identify and fix the most common layout bugs.
Check that the parent container has display: flex or display: grid with proper direction/template settings.
// Fix: Add flex container with row direction
<div className="flex flex-row gap-4">
<div>Item 1</div>
<div>Item 2</div>
</div>"Make the feature cards display in a horizontal row with equal spacing between them"
Add overflow handling and ensure proper width constraints on containers.
// Fix: Add overflow handling
<div className="overflow-hidden max-w-full">
<p className="break-words">Long content here</p>
</div>"Ensure all text containers have proper overflow handling and word wrapping"
Adjust z-index values to ensure proper stacking order. Higher z-index appears on top.
// Fix: Adjust z-index for proper stacking
<div className="relative z-10">Background content</div>
<div className="fixed z-50">Modal/overlay</div>"Ensure the modal appears above all other page content with proper z-index"
Use consistent spacing utilities throughout. Establish a spacing scale and apply uniformly.
// Fix: Use consistent spacing scale
<section className="py-16 px-4">
<div className="space-y-8">
<div className="mb-6">...</div>
</div>
</section>"Apply consistent spacing using 16px padding for sections and 32px gaps between major elements"
Use proper centering technique based on context: margin auto for block elements, flexbox for containers.
// Fix: Center content properly
<div className="flex items-center justify-center min-h-screen">
<div className="max-w-4xl mx-auto text-center">
Centered content
</div>
</div>"Center the hero section content both horizontally and vertically within the viewport"
Responsive design issues are extremely common in AI-generated sites. Here is a breakdown of problems and solutions by breakpoint.
When features do not work as expected, follow these systematic debugging steps for each common feature type.
"Fix the navigation links to properly route to the correct pages when clicked"
"Debug the contact form to properly submit data to the API and show success/error messages"
"Fix the authentication flow to properly log users in and maintain their session across pages"
"Fix the API integration to properly fetch and display data from the external service"
"Debug the Stripe checkout flow to properly process test payments and handle success/failure states"
Slow websites frustrate users and hurt SEO. Here is how to identify and fix common performance issues in AI-generated websites.
Warning sign: First Contentful Paint > 2.5s
"Optimize the page loading performance by implementing lazy loading and code splitting"
Warning sign: Frame rate < 60fps
"Fix scroll performance by optimizing animations and reducing unnecessary re-renders"
Warning sign: Memory usage grows over time
"Fix memory leaks by properly cleaning up event listeners and intervals when components unmount"
Warning sign: JavaScript > 200KB gzipped
"Reduce bundle size by implementing tree shaking and removing unused dependencies"
Deployment errors can be frustrating, but they usually have straightforward solutions. Here are the most common deployment issues and how to resolve them.
Cause: Missing dependency or incorrect import path
Solution: Run npm install, verify package is in package.json, check import path spelling
Prevention: Always run build locally before deploying
Cause: TypeScript compilation errors
Solution: Fix type errors shown in build output, add proper type definitions
Prevention: Enable strict mode and fix errors during development
Cause: Runtime error in server-side code
Solution: Check server logs for error details, verify API routes work locally
Prevention: Test all API routes before deployment
Cause: Incorrect routing or missing page file
Solution: Verify file exists in correct directory, check dynamic route parameters
Prevention: Test all routes locally before deployment
Cause: Missing environment variables in production
Solution: Add all required env vars to hosting platform settings
Prevention: Document all required environment variables
Cause: API not configured to allow requests from your domain
Solution: Configure CORS headers on API to allow your domain origin
Prevention: Test API calls from deployed domain before launch
Cause: Loading HTTP resources on HTTPS page
Solution: Update all resource URLs to use HTTPS
Prevention: Always use protocol-relative or HTTPS URLs
Cause: Incorrect asset paths or missing files
Solution: Verify assets exist in public folder, check path casing (case-sensitive on Linux)
Prevention: Use consistent lowercase naming for all assets
JustCopy.ai handles most deployment complexity automatically. With one-click deployment, SSL certificates, CDN distribution, and environment variable management are all configured for you. No build errors to debug, no server configuration needed - your website goes live in seconds, not hours.
The best debugging is the debugging you never have to do. Follow these practices to prevent common issues before they happen.
Test each major feature as you build rather than waiting until the end. This makes issues easier to isolate and fix.
Keep DevTools open during development. Watch for console errors, inspect element styles, and monitor network requests.
Design and test for mobile before desktop. Scaling up is easier than scaling down, and mobile issues are common.
Before making big changes, save your current working state. Use Git commits or export to GitHub regularly.
Error messages usually tell you exactly what is wrong. Read them carefully before searching for solutions.
When fixing issues with AI, describe the specific problem and where it occurs. Vague prompts lead to vague fixes.
Sometimes fixing issues takes longer than starting fresh. Since JustCopy.ai creates websites in under 2 minutes, knowing when to regenerate can save you significant time.
| Scenario | Action |
|---|---|
| 🔧Single element misaligned | Fix |
| 🔄Entire layout is wrong | Regenerate |
| 🔧One feature not working | Fix |
| 🔄Multiple features broken | Regenerate |
| 🔧Styling inconsistent throughout | Fix |
| 🔄Wrong technology/framework used | Regenerate |
| 🔧Performance issues | Fix |
| 🔄Design completely off-brand | Regenerate |
Start by opening browser DevTools (F12) and checking the Console for JavaScript errors. These usually point directly to the problem. Then inspect the Network tab to see if API calls are failing. For layout issues, use the Elements panel to examine CSS properties. With JustCopy.ai, you can describe the specific issue and ask the AI to fix it - the more precise your description, the better the fix.
Mobile layout issues typically stem from missing or incorrect responsive CSS. Common causes include fixed widths instead of percentages, missing media queries, or flexbox/grid not configured for smaller screens. Test at 375px width (iPhone SE) to catch most issues. When asking AI to fix it, specify the exact breakpoint and describe what's happening vs. what should happen.
Non-working buttons usually have missing onClick handlers or incorrect href attributes. Check the browser console for errors when clicking. Verify that event handlers are properly attached and that any JavaScript dependencies are loaded. For Next.js/React apps, ensure Link components are imported correctly. Ask the AI to 'make the [specific button] functional by adding the correct click handler'.
First, read the complete error message - it usually identifies the exact problem. Common issues include missing dependencies (run npm install), TypeScript errors, or missing environment variables. Always run 'npm run build' locally before deploying to catch errors early. For JustCopy.ai projects, check that all required environment variables are set in your hosting platform.
Fix when: single elements are broken, one feature isn't working, or you need minor style adjustments. Regenerate when: the entire layout is wrong, multiple core features are broken, or the design is fundamentally off-brand. Fixing preserves working code while regenerating gives a fresh start. JustCopy.ai creates websites in under 2 minutes, so regenerating is often faster for major issues.
Run a Lighthouse audit to identify specific issues. Common fixes include: optimizing images (use WebP format and next/image), enabling lazy loading for below-fold content, implementing code splitting for large components, and removing unused CSS/JavaScript. Ask the AI to 'optimize performance by implementing lazy loading and image optimization' for automatic fixes.
API failures usually come from: incorrect API keys or endpoints, CORS restrictions, missing authentication headers, or rate limiting. Check the Network tab in DevTools to see the actual error response. Verify environment variables are set correctly both locally and in production. For CORS issues, ensure your API allows requests from your website's domain.
Test early and often - don't wait until the end to check if things work. Keep browser DevTools open to catch errors immediately. Use clear, specific prompts that describe exactly what you want. Save working versions before making big changes. Check mobile layout throughout development, not just at the end. With JustCopy.ai's instant preview, you can verify each change as you make it.
