I change my phpMyAdmin's password to 'no password' then it auto log out.
I can't log in again. I think my password should be blank but it not help. how i solve my problem??
You should revert your changes back, it is possible to do the following way:
Code:
cd /usr/local/directadmin/custombuild
./build phpmyadmin
Note, it is very insecure to allow access into phpMyAdmin without password. You should never do that, unless your server is protected with firewall and access is limited by IP.
This is a very old post from 2013. I think you should describe more in the new post because some issues like the above might not be the same with the new release. Also, I doubt that you also follow his bad practice by letting PHPMyAdmin password blank. So, your issue might not be the same here. Make a new post with more info.
