  Try replacing your "require" section with this in your composer.json file:
  
  ```
  "require": {
      "craftcms/cms": "^3.0.18",
      "vlucas/phpdotenv": "^v2.4.0",
      "craftcms/redactor": "^2.1.5",    
      "dolphiq/craft3-forms": "^1.1.0",
      "craftcms/contact-form": "^2.2.2",
      "craftcms/guest-entries": "^2.1.3",
      "nerds-and-company/schematic": "^4.0.14"
    },
  
  ```
  
  Then, if you have Composer installed from the [command line](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx), run `composer update` from your project's root and let it finish.

  To do that, open up your composer.json file, and remove this line:
  
  ```
  "roave/security-advisories": "dev-master"
  
  ```
  
  If that was the last line within your `"require"` object, make sure to delete the comma at the end of the line before it, too.
