Answers.Body: <p>Your module was created for Craft 3, but you're using Craft 4. Make sure to follow the <a href="https://craftcms.com/docs/4.x/upgrade.html" rel="noreferrer">upgrade guide</a> and the <a href="https://craftcms.com/docs/4.x/extend/updating-plugins.html" rel="noreferrer">plugin update guide</a> if you're updating a site with custom modules to Craft 4.</p>
  <p>You're seeing this error because Craft 4 added <a href="https://www.php.net/manual/en/language.types.declarations.php" rel="noreferrer">type declarations</a> to most classes and methods. Custom classes that extend core classes need to be adjusted accordingly. In this case, you're extending <a href="https://docs.craftcms.com/api/v4/craft-web-controller.html" rel="noreferrer"><code>craft\web\Controller</code></a>, so your <a href="https://docs.craftcms.com/api/v4/craft-web-controller.html#allowanonymous" rel="noreferrer"><code>$allowAnonymous</code> property declaration</a> must match the declaration of the same property in the base class.</p>
  <p>Adjust the declaration like this to get rid of this error:</p>
  <pre class="lang-php prettyprint-override"><code>protected array|bool|int $allowAnonymous = ['index', 'do-something'];
  </code></pre>
  <p>Note that pluginfactory.io is being discontinued and will be shut down by the end of the year. If you're just starting out, I would also avoid using power user tools like this one. You're just including tons of code in your project that you don't understand (as you have noticed) and therefore are not able to maintain properly. Better to start from scratch with the <a href="https://craftcms.com/docs/4.x/extend/module-guide.html" rel="noreferrer">module guide</a> and make sure to understand everything you're adding to your project completely.</p>

  Your module was created for Craft 3, but you're using Craft 4. Make sure to follow the [upgrade guide](https://craftcms.com/docs/4.x/upgrade.html) and the [plugin update guide](https://craftcms.com/docs/4.x/extend/updating-plugins.html) if you're updating a site with custom modules to Craft 4.
  
  You're seeing this error because Craft 4 added [type declarations](https://www.php.net/manual/en/language.types.declarations.php) to most classes and methods. Custom classes that extend core classes need to be adjusted accordingly. In this case, you're extending [`craft\web\Controller`](https://docs.craftcms.com/api/v4/craft-web-controller.html), so your [`$allowAnonymous` property declaration](https://docs.craftcms.com/api/v4/craft-web-controller.html#allowanonymous) must match the declaration of the same property in the base class.
  
  Adjust the declaration like this to get rid of this error:
  
  ```php
  protected array|bool|int $allowAnonymous = ['index', 'do-something'];
  
  ```
  
  Note that pluginfactory.io is being discontinued and will be shut down by the end of the year. If you're just starting out, I would also avoid using power user tools like this one. You're just including tons of code in your project that you don't understand (as you have noticed) and therefore are not able to maintain properly. Better to start from scratch with the [module guide](https://craftcms.com/docs/4.x/extend/module-guide.html) and make sure to understand everything you're adding to your project completely.
