“There was an error in your submission This post type is not allowed”

Hello,

I’m using the plugin in teneriferentabike.es/galeria to give clients the opportunity to upload pictures to our galleries.

The thing is, no matter what type of file I try to upload. I always get the same message:

“There was an error in your submission This post type is not allowed”

My shortcode is:

[fu-upload-form class=”your-class” title=”Sube tu foto de una determinada ruta” form_layout=”post_media”]
[input type=”text” name=”name” id=”ug_name” class=”required” description=”Nombre”]
[input type=”text” name=”route” id=”ug_route” class=”required” description=”Ruta”]
[input type=”text” name=”email” id=”ug_email” class=”required” description=”Email”]
[input type=”file” name=”photo” id=”ug_photo” class=”required” description=”Tu/s foto/s” multiple=”true”]
[input type=”submit” class=”btn” value=”Enviar”]
[/fu-upload-form]

?Am I getting something wrong?
