My CodeIgniter website has been running unchanged for years, yet since yesterday every attempt to sign in is rejected with the “Incorrect username/password” message—even for known-good accounts. I’m not sure whether anything on the server was updated, but I do have full cPanel, SSH, and MySQL access so you can inspect code, configuration files, and logs. Here’s what I need from you: • Identify the exact cause of the failed authentication. • Implement a clean, well-commented fix that restores normal login behaviour without breaking anything else. • Provide a brief report outlining what went wrong and what you changed. The stack is classic PHP, MySQL, and CodeIgniter. Once I confirm that users can log in again, I’ll close the job immediately.

Hi, since your CodeIgniter site was stable for years and suddenly all logins fail (even valid accounts), this strongly points to a hashing/session change, PHP version update, or DB/config mismatch — I’ll trace it via logs, auth logic, and MySQL directly through SSH/cPanel. I’ll pinpoint the exact cause, restore proper authentication without breaking other modules, and keep the fix clean and fully commented. Afterward, I’ll provide a short report explaining what failed (e.g., password hashing, encryption key, session config, or PHP update impact) and exactly what was corrected. Looking forward for your positive response in the chatbox. Best Regards, Arbaz T

“I am Rajesh, with 10+ years of experience in WordPress, Laravel, PHP, ReactJS, CodeIgniter and full-stack development.” I will thoroughly investigate your CodeIgniter authentication flow to identify why valid credentials are being rejected, reviewing recent server updates, PHP version changes, session handling, encryption/hashing methods, and database integrity via cPanel, SSH, and MySQL.

If logins suddenly started failing for all users without code changes, it’s almost always a server-side change, session issue, hashing mismatch, or database/config shift. I’ve debugged and restored multiple legacy CodeIgniter auth systems where updates to PHP versions, session drivers, encryption libraries, or MySQL settings silently broke authentication. My first step would be to reproduce the issue, review error logs, and trace the authentication flow from controller to model to password verification. I’ll check for common causes such as PHP version changes affecting password hashing, session save path or cookie config issues, database collation changes, or modified config keys like encryption_key and base_url. Once identified, I’ll implement a minimal, well-commented fix that restores login behavior without touching unrelated parts of the system. You’ll receive a short report explaining the root cause, what was changed, and any preventative steps to avoid this happening again. I’m comfortable working via cPanel, SSH, and direct MySQL access, and I understand the quirks of older CodeIgniter stacks. If you’d like, I can begin by reviewing your PHP version and recent server changes to narrow this down quickly. Syed

Hello, I’m Parthkumar Virani, a PHP developer with 5+ years of experience working with CodeIgniter-based websites, including debugging sudden login/authentication failures on long-running systems. This issue is very common when something changes at the server or PHP level (PHP version upgrade, password hashing behavior, session handling, strict MySQL mode, or config changes), even if the code itself hasn’t been touched. How I’ll Handle This • Review authentication logic in the CodeIgniter app • Check password hashing/verification flow • Inspect session configuration and storage • Review database user records and encoding • Check server logs and CodeIgniter logs • Verify PHP/MySQL version compatibility • Identify the exact root cause and apply a minimal, safe fix What You’ll Get ✔ Login functionality fully restored ✔ No impact on other parts of the site ✔ Clean, commented fix ✔ Short report explaining: – What broke – Why it happened – What was changed to fix it I’m comfortable working directly via cPanel, SSH, and MySQL, and I focus on fixing the problem properly—not just bypassing it. I can start immediately and resolve this quickly once access is provided. Best regards, Parthkumar Virani
