The site at [login to view URL] has suddenly begun throwing a 500 Internal Server Error and is no longer accessible to visitors. It is an ASP.NET application hosted on Windows/IIS, and until this issue appeared it was running smoothly. I need a seasoned .NET developer to jump in, locate the root cause, and implement a clean, permanent fix so the site loads normally again. There have been no intentional code or configuration changes on my side, so the fault may lie in a recent automatic update, corrupted deployment, or server-level misconfiguration. I can provide full source code, remote access to the server (IIS + SQL Server), and any relevant log files you request. Acceptance criteria: • Identify the specific cause of the 500 error and explain it in plain language. • Patch the code or server settings so the site renders correctly on all pages. • Prove the fix by performing a fresh deploy/restart and showing the site live without errors. • Leave a short note outlining the changes made for future reference. Please be comfortable debugging production-level ASP.NET apps, reading IIS logs, and testing locally before touching the live environment. Looking forward to having the site back online quickly.
