The website being down is an issue relating to your programming on your website and nothing to do with digital ocean itself. I am assuming you are using some type of CMS or content management framework (like drupal or WordPress) and that possibly an update occurred which resulted in a PHP error.

You can log in via FTP to your server as per usual and look at the file that the error references (
‘safetyweb/plugins/system/t3/t3.php’) on the line it references (line 25). You will likely see a reference to the jPlugin class which you can address and decide what to do with based on your website setup.

Regarding login in, if your requested a new password and checked your spam folders and everything and you did not receive an email you should verify that you are using the email address that you signed up for digital ocean with. ( maybe search your inbox/archives for emails from DigitalOcean.com). If you are 100% certain that the enter you entered is correct and the password reset email is not sent to you, then you will have to contact Digital Ocean about gaining access to your account.
