I have taken over a site from another colleague who is now no longer involved with the company. I have had to transfer the hosting of my domain away from his hosting package to mine. In the transfer, the whole site has become lost. It was a WordPress-run site and I have the login details for the wp-login.php but no other username or password. The wp-login.php file seems to have gone during the transfer of the site, is there a way of re-downloading the file/site from WordPress so that I can then upload it to the new hosting server by FTP?
