@monicasynthesis

Hi, I can quickly help you fix the authentication issue on your web application caused by the PHP upgrade from 7.2 to 8.0. I will first diagnose the root cause of the “Invalid credentials” error, then update or adjust the authentication mechanism to make it compatible with PHP 8.0. Once fixed, I will test the login process thoroughly to ensure it works smoothly without errors. **QUERIES** >> Can you share which authentication system or method the application is using? >> Does the “Invalid credentials” error appear for all users or only specific accounts? Are there any related error logs in Apache/PHP error logs? >> Can you confirm the OS and Apache version running on the server? Were any other components updated along with PHP? >> Can you please share access to the server and code repository to investigate and fix the issue? I have strong experience with PHP (including PHP 8.0), Apache server configuration, and troubleshooting login/authentication problems. I’ve handled similar PHP upgrade issues before and restored functionality within tight deadlines. I’m available to start right away so you can get your site working again quickly. Please feel free to reachout so that we can discuss it further and start work. Kind regards, Monica
