Body: <p>I am taking over maintaining a website that was done in Craft CMS by a different webdeveloper (he has stoppd responding to the client). I have the login info for admin and when I go to the dashboard, when I click Entries, nothing shows up in the list. I don't know if I am looking in the wrong place. There is an error message at the top:</p>
  <p>Warning: Declaration of craft\helpers\FileHelper::getExtensionByMimeType($mimeType): string should be compatible with yii\helpers\BaseFileHelper::getExtensionByMimeType($mimeType, $preferShort = false, $magicFile = NULL) in /var/www/milne-fruit-craft-stage/vendor/craftcms/cms/src/helpers/FileHelper.php on line 719</p>
  <p>The IT department at the company is trying to get access to the AWS hosting account the previous designer set up, since they don't have the login credentials for it.</p>
  <p>Would this server error explain why I can't see the entries? Any insight would be greatly appreciated. TIA</p>

Comments.Text: Hi Beth, which version of Craft are you running? I think it's likely you'll need to update the site using composer/SSH.

Comments.Text: It looks like it's PRO 3.7.26
  
  If I try to update it and it breaks anything, we don't have server/hosting account access yet to go in and try to fix it.
  
  Do you know of a way to back up the site? I'm assuming a plugin, but the plugin store won't load, so I'm thinking I'm out of luck until we can access the server.

Comments.Text: Yeah, you will need as a minimum I think. It should just be a case of updating the Craft version in your `composer.json` to 3.9.14 (the latest version) and running `composer update` via SSH. Before that, you can try running `php craft db/backup` to take a backup.

Comments.Text: My general approach to a situation like this is to get it running locally as best you can and then try to deal with the production server. To start, at a minimum, you'll want a database backup. I haven't used Craft 3 in a while, but in Craft 4 and 5, there is a Utilities menu with a Database Backup area which has an option to download a copy of the database to your browser. If that works, you're a whole lot closer to getting the site fixed.
