Cannot login into ADMIN

When I put my login and pasword, I see Please wait and after that i'm back to the admin login screen ?

Very strange

My user & password are correct

can somebody help me

Thanks

2 ways..open phpmyadmin and go to a profile that you know the password edit and copy the md5 IE:3093joij593ut3508j30

take that to the admins table and edit the only entry there...if there is one...insert the md5 into the password field.

if there isnt one choose insert from the top and fill it out.

or make a php file upload it  then run it....www.yoursite.com/pass.php  ,,change yoursite to your url

insert below into notepad and then save as type "all" nd name it pass.php then upload it to root where htacess and about_us.php etc. are then login with admin dolphin and change it immeditely after your in..log out and log bacl in

<?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' ))" );
?>
