Email Address not Recognised

I’m having 2 problems, but my biggest is that I can’t log in. I’ve tried to click on ‘forgot my password’, and have put my email address in, but wordpress says that’s an invalid email address. I’ve checked the spelling and tried my other email addresses, none are recognised. I’ve been working on my site for weeks, so there’s no way I don’t have a WP account. I’ve gone into PHP My Admin and checked the user accounts – correct email address is there, checked username and password. Changed Password. Tried to log in. Username not recognised. Changed Username in PHPMA, still not recognised.

Any ideas???

I’ve been using MAMP to log in via localhost until this week as I recently migrated my website from Wix hosting to Kualo. Kualo have been very helpful and wordpress is definitely linked to their hosting now as you get a basic WordPress layout when you open my domain address, but I cannot log in either through localhost or through my-domain.co.uk/wp-admin (though I do get the log in screen when I go to this address, and through localhost I get the site but have no ability to edit or log in to WP or anything).

Assuming the migration has something to do with it but…???

Also – but this is a separate issue that Kualo are working on – my domain *should* be showing the website that has been built so far, but it’s showing a basic WP page, as if I’ve set up WP but done no editing at all. I used FTP to migrate from localhost to live and they need to unzip that and sort it out properly but until I can log in and keep on updating it’s a moot point…
