1. Check if URLs are selected

Make sure the checkboxes next to your URLs are checked. Only checked URLs will open.

2. Verify delay and batch size settings

Check your opening settings:

• Delay should be at least 1 second
• Batch size should be between 1-20
• Limit should be 0 (no limit) or greater than 0

3. Check browser popup blocker

Your browser may be blocking popups. To fix:

1. Look for a popup blocker icon in your address bar
2. Click it and allow popups for bulkU
3. Or go to browser settings and add bulkU to allowed sites

4. Try reducing batch size

If opening many URLs, try reducing batch size to 5 or even 1 to see if that helps.

1. Refresh the extension

1. Go to chrome://extensions/ (or your browser’s extension page)
2. Find bulkU in the list
3. Click the refresh/reload icon
4. Try opening bulkU again

2. Restart your browser

Close all browser windows completely and reopen. This often resolves loading issues.

3. Reinstall the extension

If refreshing does not work:

1. Export a backup of your data first!
2. Uninstall bulkU
3. Restart your browser
4. Reinstall from the Chrome Web Store
5. Import your backup

4. Check browser console for errors

For advanced users:

1. Open bulkU
2. Press F12 to open Developer Tools
3. Check the Console tab for error messages
4. Send these errors to support for help

1. Check browser storage permissions

1. Go to chrome://extensions/
2. Find bulkU and click “Details”
3. Ensure “Site access” is set to “On all sites”
4. Check that storage permissions are enabled

2. Check if you are in Incognito mode

By default, extensions do not save data in Incognito mode. To enable:

1. Go to chrome://extensions/
2. Find bulkU and click “Details”
3. Enable “Allow in Incognito”

3. Export backups regularly

As a precaution, regularly backup your data:

• Click “Backup All Groups” weekly
• Save the JSON file to a safe location
• You can restore from this backup anytime

4. Check available storage space

Ensure your browser has enough storage space. Clear browser cache if needed.

1. Ensure file is valid JSON format

If importing a JSON backup:

• Open the file in a text editor
• Check that it starts with { and ends with }
• Ensure no extra characters were added

2. Check file was not corrupted during download

Try exporting again and comparing file sizes. If they differ, the download may have been interrupted.

3. Try different file formats

If JSON import fails, try:

• Exporting as CSV instead
• Opening CSV in Excel, copying URLs
• Pasting directly into bulkU

4. Contact support with the file

If you still cannot import, email the file to support@bulku.app for investigation.

1. Reduce number of URLs per group

If you have hundreds of URLs in one group:

• Split them into multiple smaller groups
• Keep groups under 150 URLs for best performance
• Use tags to organize within groups

2. Increase delay between batches

When opening URLs:

• Increase delay to 3-5 seconds
• Reduce batch size to 5-10 URLs
• This gives your browser time to process

3. Clear browser cache

1. Go to browser settings
2. Find “Clear browsing data”
3. Select “Cached images and files”
4. Clear cache

4. Disable other extensions temporarily

Other extensions may conflict with bulkU. Try disabling them one by one to identify conflicts.

1. Refresh the extension

Close and reopen bulkU. Pro status should sync automatically.

2. Restart browser

Close all browser windows and reopen. This forces a fresh sync with Pro servers.

3. Check payment confirmation email

Verify that:

• Payment was successful
• You are logged into the correct account
• Email matches your bulkU account

4. Contact support with payment details

Email support@bulku.app with:

• Payment confirmation number
• Email used for payment
• Date of purchase
• Screenshot of payment confirmation
