I created a domain in weblogic with user name and password as weblogic. I went to the weblogic console and changed the password as weblogic1.Now whenever I access the console the following error is occuring
It's not clear whether you are able to login or not. Generally the password is stored in internal LDAP. You can see the content of ldap in ldift files stored in your domain directory. Password is hashed and stored so you can't see the clear text however, under your domain\server directory you will find ldap directory which contains log and backup entries. You can try to figure out from the log whether the update has been carried out. It's not going to be easy to recover or fix expect to restore from the backup directory or creating a new admin user.
