Fix Admin Panel Functionality Bugs

My travel portal handles quote generation and itinerary creation smoothly on the front end, but the Admin panel is giving me trouble. Key functions intermittently fail, blocking routine tasks such as saving edits, updating prices, and pushing new itineraries live.

I need these functionality bugs isolated, fixed, and fully tested right away so the back-office flow is reliable again. Once corrected, a quick walkthrough outlining the changes will help me keep the codebase maintainable.

To help me choose fast, include links or screenshots of past work where you resolved similar backend or dashboard issues. A concise note on how you would approach root-cause analysis and final validation is welcome too.

Turnaround is urgent; as soon as the Admin panel works flawlessly, the job is considered complete and I will release payment immediately.
