Try

PHP

$sql ="SELECT * FROM uname ='".$_SESSION['users']."'";

Your code is vulnerable to SQL injection.
Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.

If you want to ask a question, then ASK A QUESTION[^]. DO NOT post your question as a "solution" to someone else's question.

But be warned, you're going to have to provide a lot more than a random error message if you want anyone to be able to help you.
