Quickly diagnose and fix common DesignSetGo plugin issues.

What's the Problem?

•Build errors - npm run build fails
•Styles not applying - Editor or frontend styles missing
•Block validation error - "This block contains unexpected or invalid content"
•Console errors - JavaScript errors in browser console
•Layout not working - Grid/flex/stack layout broken
•Colors not showing - Theme colors missing from picker
•Translation missing - Strings not translating
•wp-env not starting - Local development environment issues

Fix 1: Build Errors

Symptoms: npm run build fails with errors

Quick fixes:

bash

# Clear everything and rebuild
rm -rf node_modules build
npm install
npm run build

# Check for syntax errors
npm run lint:js
npm run lint:css
npm run lint:php

# If specific file error, check that file for:
# - Missing imports
# - Syntax errors (missing brackets, semicolons)
# - Typos in function names

Fix 2: Styles Not Applying

Editor Styles Missing

bash

# 1. Check if styles are imported in editor.scss
grep "@import" src/styles/editor.scss

# 2. Verify build output
cat build/index.css | grep "your-class-name"

# 3. If missing, add import to src/styles/editor.scss
# @import '../blocks/your-block/editor';

# 4. Rebuild
npm run build

Frontend Styles Missing

bash

# 1. Check if styles are imported in style.scss
grep "@import" src/styles/style.scss

# 2. Verify build output
cat build/style-index.css | grep "your-class-name"

# 3. If missing, add import to src/styles/style.scss
# @import '../blocks/your-block/style';

# 4. Rebuild
npm run build

CRITICAL: Both style.scss and editor.scss must import block styles.

Fix 3: Block Validation Error

Symptoms: "This block contains unexpected or invalid content" or block shows recovery prompt

Common causes:

•Edit and save markup don't match

javascript

// ❌ WRONG - Different structure in edit vs save
// edit.js
<div {...blockProps}>
    <div className="inner">
        <InnerBlocks />
    </div>
</div>

// save.js
<div {...blockProps}>
    <InnerBlocks.Content />
</div>

// ✅ CORRECT - Identical structure
// Both edit.js and save.js:
const innerBlocksProps = useInnerBlocksProps(...);
<div {...innerBlocksProps} />

•Attributes changed without deprecation

javascript

// If you changed attributes, add deprecation:
// block.json
{
  "deprecated": [
    {
      "attributes": { /* old attributes */ },
      "save": OldSaveComponent
    }
  ]
}

•Using plain <InnerBlocks /> instead of useInnerBlocksProps

javascript

// ❌ WRONG
<InnerBlocks />

// ✅ CORRECT
const innerBlocksProps = useInnerBlocksProps();
<div {...innerBlocksProps} />

Fix 4: Console Errors

Check browser console for specific errors:

"Cannot find module '@wordpress/...'"

javascript

// Add proper import
import { __ } from '@wordpress/i18n';

"useSelect is not a function"

javascript

// Import from correct package
import { useSelect } from '@wordpress/data';

"Attribute is undefined"

json

// Add default in block.json
{
  "attributes": {
    "yourAttribute": {
      "type": "string",
      "default": ""
    }
  }
}

"Invalid hook call"

javascript

// Move hooks outside conditionals
// ❌ WRONG
if (condition) {
    const value = useSelect(...);
}

// ✅ CORRECT
const value = useSelect(...);
if (condition && value) {
    // use value
}

Fix 5: Layout Not Working

Symptom: Grid/flex/stack not applying to blocks

Fix: Use useInnerBlocksProps instead of plain <InnerBlocks />

javascript

// ❌ WRONG - Plain InnerBlocks
<div style={{ display: 'grid' }}>
    <InnerBlocks />
</div>

// ✅ CORRECT - useInnerBlocksProps
const innerBlocksProps = useInnerBlocksProps({
    style: {
        display: 'grid',
        gridTemplateColumns: 'repeat(3, 1fr)',
        gap: '20px'
    }
});

return <div {...blockProps}><div {...innerBlocksProps} /></div>;

Save function must match:

javascript

// save.js
const innerBlocksProps = useInnerBlocksProps.save({
    style: {
        display: 'grid',
        gridTemplateColumns: 'repeat(3, 1fr)',
        gap: '20px'
    }
});

return <div {...blockProps}><div {...innerBlocksProps} /></div>;

Fix 6: Colors Not Showing

Symptom: Theme colors missing from color picker

Fix: Migrate to ColorGradientSettingsDropdown

See /color-controls-migrate command for complete migration guide.

Quick check:

bash

# Are you using deprecated PanelColorSettings?
grep -r "PanelColorSettings" src/blocks/your-block/

# If yes, run:
# /color-controls-migrate

Fix 7: Translation Missing

Symptom: Strings appear in English instead of target language

Quick fixes:

bash

# 1. Regenerate POT file
npx wp i18n make-pot . languages/designsetgo.pot

# 2. Update PO files
msgmerge --update languages/designsetgo-nl_NL.po languages/designsetgo.pot

# 3. Compile MO files
msgfmt languages/designsetgo-nl_NL.po -o languages/designsetgo-nl_NL.mo

# 4. Clear WordPress cache
# In wp-admin: Go to Settings → General → Site Language → Save Changes

Check for untranslated strings:

bash

# Find hardcoded strings
grep -r "'[A-Z][a-z]" src/ --include="*.js" | grep -v "__("

See /i18n-update for complete workflow.

Fix 8: wp-env Not Starting

Symptoms: npx wp-env start fails

Quick fixes:

bash

# Stop all containers
npx wp-env stop

# Remove and restart
npx wp-env destroy
npx wp-env start

# Check Docker is running
docker ps

# If Docker not running, start Docker Desktop

# Check ports aren't in use
lsof -i :8888
lsof -i :8889

# Kill processes using ports if needed
kill -9 PID

General Troubleshooting

Clear everything and start fresh:

bash

# Stop wp-env
npx wp-env stop

# Clear build and dependencies
rm -rf node_modules build

# Reinstall and rebuild
npm install
npm run build

# Restart wp-env
npx wp-env start

Check plugin in browser:

•Open browser console (F12)
•Check for errors in Console tab
•Check Network tab for failed requests
•Look for specific error messages

Before Asking for Help

Run this diagnostic:

bash

# Check versions
node --version  # Should be 18+ or 20+
npm --version

# Check build status
npm run build

# Check linting
npm run lint:js
npm run lint:css

# Check tests
npm test

# Check wp-env
npx wp-env start
