Plugin being used only appears if user registration is on. Need help with PHP

I want to put a login form in my sidebar. I have tried MiniMeta as well as others and found that they did not work on my blog.

This is the plugin I have found works:
https://www.wpdesigner.com/2007/07/14/my-account-widget/
It appears that this plugin is no longer being supported by its author.

The problem I am running into is that the “Anybody can register” option needs to be turned on for the login form to appear, but I do not want to have this option available.

Can somebody please tell me what I need to change in the PHP so that the form appears even if the registration option is turned off?

Here is the snippet of code that I believe needs to be changed:

<?php elseif ( get_option(‘users_can_register’) ) : ?>

<h2>Identification</h2>

• <form action=”<?php bloginfo(‘url’) ?>/wp-login.php” method=”post”>
  <p>
  <label for=”log”><input type=”text” name=”log” id=”log” value=”<?php echo wp_specialchars(stripslashes($user_login), 1) ?>” size=”22″ /> User</label>
  <label for=”pwd”><input type=”password” name=”pwd” id=”pwd” size=”22″ /> Password</label>
  <input type=”submit” name=”submit” value=”Send” class=”button” />
  <label for=”rememberme”><input name=”rememberme” id=”rememberme” type=”checkbox” checked=”checked” value=”forever” /> Remember me</label>
  </p>
  <input type=”hidden” name=”redirect_to” value=”<?php echo $_SERVER[‘REQUEST_URI’]; ?>”/>
  </form>
• /wp-register.php”>Register
• /wp-login.php?action=lostpassword”>Recover password

<?php endif // get_option(‘users_can_register’) ?>
