Admin login failed

if you reinstalled it might have went back to the default name and password, username admin and password dolphin if I rem lol

the only way I can think of is to go into the database and look there. The password is going to be encrypted. But you can do a search on goole for MD5 encryption and decode it.
If you need some help with this feel free to Email me. I will be more than happy to assist

I think it's a bug. Some months ago I tried Dolphin too and installed it on a local server. Same problem: I couldn't login as admin. Now I try Dolphin 6 an nothing's changed sorry I thougt Dolphin was improved by version 6

Found this fix and it worked.

Dear customers!
We are sorry for the inconvenience, but there was a problem with the save option for admin login in the Dolphin 6.0.0001 patch. To fix this problem please do the following:

1 Create a txt file for example "admin_fix.php".
2 Insert the following code there

<?php
include( "inc/header.inc.php" );
include( "inc/db.inc.php" );
db_res( "TRUNCATE TABLE `Admins`" );
db_res( "INSERT INTO `Admins` (`Name` ,`Password`) VALUES ('admin', MD5( 'dolphin' ))" );
?>

3 Copy and paste this file into Dolphin's root folder
4 Run this file in your favourite browser - for example http://www.yoursite.com/dolphin/admin_fix.php

5. Enter your Admin Panel and change the password to one of yours (difficult to guess pass). Since the file above sets new default password "dolphin".
