cPanel File Upload Not Working

If you have encountered an issue about file uploading on the cPanel, this is the right guide to get the solution. We have mentioned the clear steps and fixes for diagnosing and resolving the problem. Let’s delve deeper into the article highlighting common issues about the file upload in the cPanel. 

Why File Upload Issues Occur in cPanel?

File upload issues in cPanel stem from several underlying factors, including file size limitations, permission issues, and even network connectivity. Understanding these causes helps in diagnosing and fixing the problem effectively.

Here are Some Common Causes:

• File Size Restrictions: cPanel has default limitations on the size of files you can upload. Attempting to upload files that exceed this limit results in an error. 
• Permission Issues: If permissions are incorrectly configured, cPanel might restrict you from uploading files. 
• Browser or Cache Problems: Sometimes, the browser cache or settings might conflict with cPanel’s interface, causing upload failures.
• Insufficient Storage: Low storage on your hosting server can also prevent file uploads.
• Network Connectivity Issues: A poor internet connection or firewall settings could be blocking your upload attempts.
• PHP Configuration Limits: Hosting servers running PHP have certain configurations, such as upload limits, which may restrict file sizes or timeout settings.

Let’s dive into solutions for these issues to get your file uploads working again.

Step-by-Step Solutions for Fixing cPanel File Upload Issues

1. Check File Size Limits

Ensure that you are not surpassing the file upload limits, review th file size limitations in your cPanel configuration. 

• Locate File Size Limits: Open the cPanel File Manager, go to the upload section, and note the maximum allowed file size. Alternatively, check the PHP settings in your cPanel under Select PHP Version > Options to confirm the upload_max_filesize and post_max_size values.
• Increase File Size Limit (if possible): MilesWeb allows to increase the file size limit of the server space. Otherwise, consider compressing the file or breaking it into smaller parts for upload.

2. Update File Permissions

If you encounter permission errors, you might need to adjust file permissions.

• Check Permissions: In the File Manager, right-click the folder where you want to upload files, select Permissions, and ensure permissions are set correctly (often 755 for directories and 644 for files).
• Modify Permissions: If permissions are too restrictive, adjust them within reasonable bounds to allow file uploads. Avoid setting permissions to 777 as this can expose your files to security risks.

3. Clear Browser Cache 

Your browser settings or cached files may sometimes conflict with cPanel, causing unexpected upload errors.

• Clear Cache: Go to your browser settings and clear cache and cookies. Restart your browser and try uploading again.
• Switch Browsers: If clearing the cache doesn’t work, try a different browser or use an incognito/private browsing window.

4. Modify PHP Configuration Limits

PHP configuration settings can directly impact file upload capabilities. For example, settings like upload_max_filesize and post_max_size determine the largest file you can upload.

Adjust PHP Settings: In cPanel, go to Select PHP Version > Options and increase the values for upload_max_filesize, post_max_size, and max_execution_time. Make sure the file size limits are large enough for your intended upload.

5. Preventing Future cPanel Upload Issues

To reduce the chances of future upload issues, it’s helpful to follow these best practices:

• Optimize Files: Compress files before uploading to avoid size-related errors.
• Regularly Clear Cache: Periodically clear your browser cache to prevent potential conflicts with cPanel.
• Monitor Disk Space: Keep an eye on server storage and ensure you have enough room for new files.
• Review Hosting Limits: Regularly review your hosting plan and its limitations to see if you need an upgrade.
