Dear sir,
Thank you so much for your responses. I'm actually struggling hard to get the software installed. Everything seems to be fine expect the login credentials. As per the provided link I've tried changing the admin password too as the attached image. This also seems to be okay without any error. But, still I'm not able to log in.
And for getting password from PHPMyAdmin, I'm also not able to get it from there.
P.S. I have tried installing the latest stable version including the previous ones. Every time the issue is same for me
Thank & regards
Ankana
