I have very limited knowledge of Web programming stuff. I am working as a technical support for a company which has an intranet which I believe was created using XAMPP. The previous support person left the company and did not leave any documentation about this. We are currently having some problems with it. Our users cannot login the Web site to modify contents. When they put in their username and password, it flashes and then goes back to the homepage. It does not give any error message about incorrect username or password. When we tried the link "Forgot your username" and "Forgot your password", it asked for email address to send the reset information but nothing was sent out to users.
On the server, I have tried to access the XAMPP Control Panel > PHPMyAdmin >Joomla >Jos_users table and edited the password for one of the users but he still cannot login.
I am guessing maybe somehow the authentication mechanism is not working properly.
Could someone give me some help please.
Thank you much.
