GOautodial Open Source Omni-channel Contact Center Suite

Sir i Installed Goautodial 3.0 32 bit release on my virtual machine. Its working prefect until i change the admin Phone login and password. After that i am unable to login in the web interface of Goautodial . I have not changed the password of the Admin. Also agents are not able to login it says Login Failed. I checked the mysql Vicidial_user and checked admin user entry. Password is the default one.

Last Action Log Recorded in goauto db table go_action_log is as follows
action Field shows
Modify

Details field shows
Modify vicidial_user user_id = 3 and vicidal_phones phone_login = 8888

Db Querry field shows the following entry
show columns from vicidial_users where field = \'users_id\' \nshow columns from vicidial_users where field = \'vicidial_user_id\' \nshow columns from vicidial_users where field = \'pass\' \nshow columns from vicidial_users where field = \'full_name\' \nshow columns from vicidial_users where field = \'phone_login\' \nshow columns from vicidial_users where field = \'phone_pass\' \nshow columns from vicidial_users where field = \'user_group\' \nshow columns from vicidial_users where field = \'active\' \nshow columns from vicidial_users where field = \'hotkeys_active\' \nshow columns from vicidial_users where field = \'user_level\' \nUPDATE `vicidial_users` SET `pass` = \'goautodial\', `full_name` = \'Admin\', `phone_login` = \'8888\', `phone_pass` = \'8888\', `user_group` = \'ADMIN\', `active` = \'Y\', `hotkeys_active` = \'1\', `user_level` = \'1\' WHERE `user_id` = 3 \n

After this entry following entries are there

Action field shows
WRONG AUTHENTICATION

Details Field Says
not authenticated

I have not done other thing than changing phone login and phone pass change. Done this on fresh installation so as to check the issue

Please help
