WordPress Site Repair Needed

My WordPress site has started misbehaving—pages drop into endless loading loops, the dashboard sometimes freezes, and a couple of features that used to work now throw mysterious errors. I’m looking for someone who can jump in, trace the root cause, and get everything running smoothly again.

You’ll begin with a full diagnostic (core files, theme, and plugin conflicts) and then implement a clean, documented fix. Once resolved, I’d like the site loading quickly, free of PHP or console errors, fully compatible with the current WordPress version, and secured against obvious vulnerabilities.

When the work is done, please provide a short summary of what you found, what you changed, and any recommendations for future maintenance so I can avoid repeat issues. If you’re comfortable troubleshooting WordPress core, themes, PHP, MySQL, and common hosting panels, I’m ready to get this sorted right away.
