How to Troubleshoot a cPanel Website That Stops Receiving Form Uploads

A website can accept text forms while file attachments fail because of upload limits, temporary storage, account quotas, permissions, or a security rule. The form may still show a generic success message.

What to check

Check PHP and application upload limits, temporary directory capacity, account disk and inode use, destination permissions, and security logs. Test a small and boundary-sized file and verify whether it reaches the application.

Recommended next step

Correct the limiting layer, provide an accurate error message, and validate accepted file types and sizes. Ensure uploaded files are stored safely and do not execute as web content.
