I tried installing SuiteCRM 8 beta version. Even after successful installation I am not able to login. It says Login credentials incorrect, please try again.
first thing I remember my user and pass which I gave while installation.
second, I replaced with another password in the users table, still it doesnt work.
Capslock is checked

Welcome @Guneet!

This has been identified as a bug by the core team. Did you include demo data? If so try logging in with the demo user/password. If not, then try and add another user physically to the database.
