The error is that I dont have the right credentials. (I think it will be useless if I show screenshot about when I tried to log in to many times). I used All-in-One WP Migration Unlimited Extension Version 2.31. (I'm not sure if this was the version I installed on Bitnami)
I work with Wordpress (using woocommerce) and my host is Siteground
I installed the Bitnami.
I logged in
I installed All-in-One WP Migration Unlimited Extension
I installed a backup
Everything worked for a while but I took a break and when I needed to log in again
I could not log in
Now it gives me the option again to log in but I dont have a clue what username
and password to use?
