My website’s front-end and admin screens are suddenly riddled with PHP errors that trace back to the core WordPress files rather than the theme or plugins. I need a developer who can dive straight into the codebase, locate the conflicts, and restore full stability and speed within the next few hours. Here’s what success looks like to me: • Diagnose and eliminate the PHP errors now appearing in core WordPress files, documenting the root cause and each change you make. • Patch any related security vulnerabilities you uncover while working. • Optimise load time once the errors are resolved so pages render quickly on desktop and mobile, without breaking existing functionality. • Verify the site operates flawlessly across major browsers (Chrome, Firefox, Safari, Edge) and devices. • Provide a concise hand-over report outlining the fixes, preventive steps, and any future recommendations. Access to the server, WP-CLI, and error logs will be supplied immediately after project award, and I’ll stay available on chat for rapid feedback. If you have deep WordPress core experience, solid PHP debugging skills, and can start right away, let’s get this site back to perfect health.
