I can't access my website or my dashboard

If you’ve previously been able to access the site with no problems, then this probably means something is wrong with your web host’s database server. You might want to contact them just to make sure they are aware of it.

UPDATE: And now checking your site, it appears to come up. Probably just a temporary server issue.

It’s fixed. My provider noticed the password had been changed, fixed it(not sure what they did) and it’s working now.
