Admin failed to login

[IntoRain]

Hello! I followed the guide to installing and I did the installation process twice. When I finish it and try to login it always says login failed because of the details specified. I'm quite sure it's the right username and password... The user is there in the members list. I tried to retrieve my lost password but I got no emails in 2 hours of wait.

I'm sorry if this is a stupid problem but I really can't figure out why it's acting like that

I'm using x10hosting with the most recent mysidia version and I didn't mess with the code yet. I noticed this issue happened with other users but in older versions, so I don't really understand it... I went to check the database and the user is indeed there, changed the password and everything and nope...
