[SOLVED] Admin login Crazy

[myshipper]

I successfully log in but the page is blank no matter what i name the admin folder
after i log in it adds the last character like these

http://......com/admin123/3/
http://......com/admin12/2/
http://......com/admin1/1/
http://......com/admino/o/

can anyone explain why this is happening
after log in if i try to remove the added character and use index.php
it asks to log in again and then it repeats the same crap

I FOUND OUT WHAT HAPPENED THERE WAS A SPACE IN THE URL AFTER RENAMING AND REDOING THE
DATABASE INSTALL EVERYTHING OK IN CASE SOMEONE ELSE HAS THIS PROBLEM
