How to Diagnose Website Errors After a cPanel PHP Version Change

11/11/2026

A PHP version change can expose removed functions, extension differences, stricter typing, or different per-account settings.

Checks to make

Record the previous and current versions, inspect the application error log, confirm required extensions and PHP options, and reproduce on staging if available. Restore the supported version as a temporary recovery only after preserving error details and planning an application fix.
