My WordPress installation falls over the moment traffic spikes, and a handful of internal pages now throw 404s. I’m looking for someone who can dive straight into functional debugging, find the root cause of the crashes, and get every broken link or page loading again—without touching the design. Your job is to reproduce the issue under load, isolate the code, database, or server configuration responsible, and apply a clean fix that keeps the site stable during peak periods. As you work, please audit for broken internal links and repair or redirect them so the whole site responds correctly. Feel free to leverage tools such as WP-CLI, Query Monitor, New Relic, or any other profiler you trust, and recommend plugin changes only if they materially improve performance. We’ll start on a staging copy; once you’ve supplied a concise report of what you changed and proven—via load testing—that the crashes and 404s are gone, we’ll move it to production. Let me know the access you’ll need and an estimated turnaround time so we can get started right away.
