How to Troubleshoot cPanel Websites That Cannot Process Large Form Submissions

Large submissions may exceed PHP request limits, web server body limits, timeouts, or account resource capacity.

Checks to make

Capture the safe request size and error, compare PHP upload and post limits with server and proxy limits, and inspect account resources. Align limits across layers only as needed and validate that application-side validation remains active.
