WordPress Bug Fix: Cannot Edit Pages (Blank White Screen)

I am looking for an experienced CMS / WordPress Developer to troubleshoot and fix a critical backend issue on my website. The Problem: Currently, I cannot edit any of my pages. When I navigate to my WordPress dashboard and click "Edit" on a page, the screen turns completely white and stays blank (White Screen of Death). The front end of the website is still visible to users, but the backend page editor is completely inaccessible. Required Skills: * Advanced WordPress troubleshooting and core architecture knowledge * Strong PHP debugging skills (diagnosing fatal errors, memory leaks) * Experience resolving plugin, theme, and server environment conflicts * Familiarity with debugging tools (wp-config.php, debug.log) Your Responsibilities: 1. Safely diagnose the root cause of the error (likely by enabling WP_DEBUG or performing a conflict test). 2. Fix the underlying PHP error or memory issue so the page editor loads properly. 3. Ensure no data is lost and the live site remains completely unaffected during the fix.
