Plugin not working

After install and save the settings, I’ve printed the debug info:

✔ PHP GD library is installed.
✔ Image cache directory has been created.
/home/user/public_html/wp-content/cache/adaptive-images => drwxr-xr-x
✔ Installation .htaccess file is setup OK.
/home/user/public_html/.htaccess => -rw-r–r–

❖ Adaptive images settings dump:

array(14) {
  ["resolutions"]=>
  array(3) {
    [0]=>
    int(1024)
    [1]=>
    int(640)
    [2]=>
    int(480)
  }
  ["landscape"]=>
  bool(true)
  ["cache-directory"]=>
  string(21) "cache/adaptive-images"
  ["watched-directories"]=>
  array(2) {
    [0]=>
    string(18) "wp-content/uploads"
    [1]=>
    string(17) "wp-content/themes"
  }
  ["jpeg-quality"]=>
  int(90)
  ["sharpen-images"]=>
  bool(true)
  ["watch-cache"]=>
  bool(true)
  ["browser-cache"]=>
  float(365)
  ["hidpi"]=>
  bool(false)
  ["cdn-support"]=>
  bool(false)
  ["version"]=>
  string(6) "0.6.62"
  ["sanitized"]=>
  bool(true)
  ["wp-content-dir"]=>
  string(37) "/home/user/public_html/wp-content"
  ["wp-content-url"]=>
  string(35) "https://www.equipados.cl/wp-content"
}

And in my .htaccess:

# BEGIN Adaptive Images
#=======================

<IfModule mod_rewrite.c>

    RewriteEngine On

    # Watched directories
    RewriteCond %{REQUEST_URI} /wp-content/uploads [OR]
    RewriteCond %{REQUEST_URI} /wp-content/themes

    # Redirect images through the adaptive images script
    RewriteRule \.(?:jpe?g|gif|png)$ /wp-content/plugins/adaptive-images/adaptive-images-script.php [L]

</IfModule>

# END Adaptive Images

I’ve tried using ?debug=true but return the image, where can I continue looking to solve this problem?
