File Upload Not Working in cPanel

If you’re unable to upload files through cPanel File Manager, it can stop you from updating your website, installing scripts, or managing media files. In most cases, this issue is related to file size limits, browser problems, permission restrictions, or temporary server resource limits.

This guide will help you quickly identify the cause and fix file upload problems inside cPanel.

Common Symptoms

You may be facing this issue if:

• Upload progress bar freezes or never completes.
• Files fail to upload without an error message.
• Uploads complete, but files do not appear in File Manager.
• You receive an error like upload failed or HTTP error.
• Only small files upload successfully, but large files fail.
• File Manager becomes unresponsive during uploads.
• ZIP file extraction fails after upload.
• Upload speed is extremely slow or stuck at 0%.

Common Causes

File upload issues in cPanel are usually caused by:

• File size limits (PHP upload limits).
• Browser cache or corrupted session.
• Weak or unstable internet connection.
• Server resource limitations.
• Incorrect folder permissions.
• Disk space quota reached.
• Security rules blocking uploads.
• Large ZIP files or timeouts during upload.
• Antivirus or firewall interference.

Solution 1: Check File Size Limits

One of the most common causes is exceeding the server upload limits.

Your hosting account has limits such as:

• upload_max_filesize
• post_max_size
• max_execution_time

If your file is larger than allowed, upload will fail silently or stop midway.

Try uploading a smaller file first to confirm.

If small files work but large files fail, the issue is likely a size limit.

Solution 2: Refresh and Retry Upload

Temporary session issues can interrupt uploads.

Try:

• Refreshing the File Manager page
• Logging out and logging back into cPanel
• Restarting your browser
• Trying the upload again

This often resolves temporary upload freezes.

Solution 3: Use a Different Browser

Some browsers handle cPanel uploads better than others.

Try uploading using:

• Google Chrome
• Mozilla Firefox
• Microsoft Edge

If the upload works in another browser, the issue is likely browser-related.

Solution 4: Disable Browser Extensions

Extensions can interfere with upload requests.

Temporarily disable:

• Ad blockers
• Privacy tools
• Script blockers
• VPN browser extensions

Then retry the upload.

Solution 5: Check Your Disk Space

If your hosting account is full, uploads will fail immediately.

In cPanel:

1. Go to Disk Usage
2. Check available storage
3. If full, remove unnecessary files such as:
   • Old backups
   • Cache files
   • Large ZIP archives
   • Unused media

Once space is freed, try uploading again.

Solution 6: Verify Folder Permissions

Incorrect permissions may block file uploads.

Recommended settings:

• Folders: 755
• Files: 644

If the target folder has restricted permissions, File Manager may fail silently.

Solution 7: Try Uploading Smaller Files First

If large files fail but small ones work, the issue is usually related to:

• PHP limits
• Timeout settings
• Server upload restrictions

To confirm:

• Upload a small text file or image
• Then try your original file again

Solution 8: Compress Files Before Uploading

Uploading multiple files individually can sometimes cause failures.

Instead:

• Compress files into a .zip archive
• Upload the ZIP file
• Extract it using File Manager

This reduces upload time and avoids connection interruptions.

Solution 9: Check Internet Stability

Unstable connections can interrupt uploads without showing errors.

Try:

• Switching to a different network
• Using mobile hotspot
• Avoiding VPN during upload

Then retry the upload.

Solution 10: Use FTP Instead of File Manager

If File Manager continues to fail, FTP is a more reliable alternative for large uploads.

You can use:

• FileZilla
• WinSCP
• Cyberduck

FTP is especially useful for:

• Large websites
• Bulk file uploads
• Slow or unstable connections

Solution 11: Check for Security Restrictions

Some security systems may block uploads.

This can include:

• ModSecurity rules
• Hosting firewall
• Antivirus software

If uploads fail consistently, temporarily disable strict security rules (if available) or contact support.

Solution 12: Try Uploading to a Different Folder

Sometimes a specific directory has issues.

Try uploading to:

• /public_html/
• A newly created folder

If it works elsewhere, the original folder may have permission or corruption issues.

Solution 13: Contact VeerHost Support

Best Practices

To avoid upload issues in the future:

• Keep file sizes optimized (compress images and assets).
• Use ZIP files for bulk uploads.
• Regularly clean up unused files.
• Monitor disk usage in cPanel.
• Avoid uploading very large files via File Manager.
• Use FTP for large projects.
• Keep browser and system updated.

Following these practices will make file uploads smoother and reduce interruptions when managing your website through cPanel.
