can't log into admin panel

What type of error message ?

i can not signin to my log into admin panel

I can't log in too. Pls tell us how to fix.

i tried reinstalling several time, but each time i tried to log in to the admin panel using the user name n password i set during the installation i still get the error msg....y?

I couldn't sign in either. after trying some of the suggestions here, I discovered that the default value for the username (in phpMyAdmin) was 10 characters max. my original username was over 10 characters so it became clear that only the first 10 characters were saved. so go to your dolphin login page and just enter the first 10 of your username. also, the default value for the password is 32 characters max, it think. so if you're password is over 32, then you'll obviously have the same issue there. see more to change these values, log into your phpMyAdmin, select your database, select "admins". You'll see two fields for "name" and "password" and their corresponding types "varchar(10)" and "varchar(32)"edit the values there if needed. Hope this helps. It stumped my brother and I for a bit, and we reinstalled dolphin about 8 times between the two of us, thinking we had made a type somewhere. good luck!
