WordPress Troubleshooting Assistance Needed

My WordPress site has begun throwing errors after I carried out some user-management changes in the dashboard. I need an experienced troubleshooter who can quickly identify what’s going wrong, resolve the underlying issue, and get everything running smoothly again.

Here’s what I expect:
• Pinpoint the root cause of the current problem (PHP conflict, database hiccup, permission mismatch—whatever is hiding behind the error messages).
• Apply a clean fix that won’t break themes, plugins, or future updates.
• Document the steps you take so I have a clear record for future reference.


If you’ve rescued WordPress installs from similar problems, I’d love to hear how long it took and what approach you used.
