Fatal error after updating or installing Elementor

The fatal error appears when Elementor cannot load required code after an update. It happens because the plugin, WordPress core, or PHP environment are not aligned.

When the mismatch occurs, PHP throws an uncaught error or type error, stopping the request and showing a blank screen or 500 error.

Symptoms

[dashicons-warning]
White screen
Your site shows a blank page with no HTML output.
[dashicons-admin-generic]
WP‑Admin inaccessible
Login redirects to recovery mode or displays a fatal‑error message.
[dashicons-editor-code]

[dashicons-no-alt]
500 error in Elementor editor
Server Error (500) appears when you click Update.

Common Causes

Version incompatibility
WordPress, Elementor, and Elementor Pro run on different release versions.
PHP version mismatch
Elementor uses functions unavailable in your current PHP runtime.
Plugin conflict
Another plugin calls a function that Elementor expects, causing an uncaught error.
Insufficient PHP memory
Server runs out of memory while Elementor processes the request, leading to a fatal error.
