Fix 500 Error in Elementor

When I try to hit “Publish” on one particular Elementor-designed page, WordPress throws a 500 Internal Server Error. Other pages publish just fine, and I haven’t installed any new plugins or themes recently, nor have I changed anything on this page before the error appeared.

I need someone who can quickly trace the cause—whether it’s a PHP conflict, memory limit, corrupted Elementor section, or something hiding in the server logs—and restore normal publishing without affecting the rest of the site. WordPress and Elementor are both up to date; access to the dashboard, cPanel, FTP and logs can be provided right away.

Acceptance criteria
• The page publishes successfully with Elementor’s changes intact
• No new errors appear elsewhere on the site
• A brief explanation of what went wrong and how you fixed it

If you have solid experience debugging 500 errors in WordPress/Elementor environments, I’d love your help.
