## ❌ Problem Still Exists If:

- You see only a label "Obsah stránky" with nothing below it
- You see a thin line but no toolbar buttons
- The area is there but you can't click or type

## 🔧 If Still Not Working

### Check 1: Hard Refresh
Press: `Ctrl + Shift + R` (Windows/Linux) or `Cmd + Shift + R` (Mac)

### Check 2: Console Errors
1. Press `F12` to open DevTools
2. Click **Console** tab
3. Look for red error messages mentioning "Quill" or "react-quill"
4. Share error message if you see one

### Check 3: Inspect Element
1. Press `F12` → **Elements** tab
2. Press `Ctrl + F` → Search for: `ql-toolbar`
3. **If found:** It's a CSS issue → See Solution A below
4. **If not found:** It's a component issue → See Solution B below

## Solution A: CSS Issue (Element exists but hidden)

Add this temporary override in browser console:

```javascript
// Paste this in Console tab and press Enter
document.querySelectorAll('.ql-toolbar, .ql-container, .ql-editor').forEach(el => {
  el.style.display = 'block';
  el.style.visibility = 'visible';
  el.style.opacity = '1';
  el.style.minHeight = '200px';
});
```

If editor appears after this, the CSS fix needs to be stronger.

## Solution B: Component Issue (Element doesn't exist)

Check package installation:

```bash
cd frontend
npm list react-quill quill
```

Expected output:
```
├── quill@2.0.3
└── react-quill@2.0.0
```

If missing or different version:
```bash
npm install react-quill@2.0.0 quill@2.0.3 --save
```

## 🎯 Success Checklist

- [ ] Toolbar with buttons is visible
- [ ] Editor area (white/gray box) is visible
- [ ] Can click inside editor area
- [ ] Can type text
- [ ] Toolbar buttons respond to clicks
- [ ] Bold/Italic formatting works
- [ ] Can change text size/headers

## 📞 Still Having Issues?

Provide this information:

1. **Browser:** Chrome/Firefox/Safari/Edge + version
2. **Console errors:** Any red errors in F12 → Console
3. **Element exists?** Search "ql-toolbar" in F12 → Elements
4. **CSS applied?** Inspect `.ql-editor` → Computed styles → Check:
   - `display: block`?
   - `visibility: visible`?
   - `min-height: 200px`?

## 🔍 Debug Commands

### Check if Quill is loaded:
```javascript
// In browser console
window.Quill !== undefined  // Should be true
```

### Check if React Quill rendered:
```javascript
// In browser console
document.querySelectorAll('[class*="ql-"]').length  // Should be > 0
```

### Force reload all stylesheets:
```javascript
// In browser console
document.querySelectorAll('link[rel="stylesheet"]').forEach(link => {
  link.href = link.href + '?reload=' + Date.now();
});
```

**Expected Time to Fix:** < 5 minutes after rebuild
