Fix Elementor Update Issue

The site https://arinsamaquinaria.com/ suddenly refuses to let me update any page with Elementor; every attempt throws error messages and the editor never loads. I have already deactivated all non-essential plugins, brought WordPress up to date, and cleared every cache I can reach, yet the problem persists.

I need a WordPress specialist who can:
• Diagnose why Elementor will not open or save changes (I am unsure whether the install is Free or Pro).
• Repair any underlying conflicts or corrupted files so editing works smoothly again.
• Run a quick “health audit” of the whole installation—theme, plugins, database, PHP settings—and clean up anything that could cause similar issues later.

Acceptance: Elementor opens, pages save without errors, and the site continues to load normally once your fixes are applied.
