Wordpess update login issues

well, first off, the reason your page is messed up, is because the style.css file is missing (or you are pointing to the wrong one) as for can’t log in, did you change the url recently? (i.e. is it pointing to .co.uk when previously it was pointing to /wp), is it giving you an error when you try to login? what exactly is the problem you are encountering?

Thanks for that. However we have not changed anything all that happened was we did an update. It is coming up with the username-password page which we are entering correctly then it re-loads the same page with no warnings and with the information filled in the boxes.
