Perch Forms not parsing

Hi, I have installed Perch Forms but for some reason <perch:form> shows on source. And form section on perch panel tells me: No forms have been submitted yet. Submit a new form to have it show up here.

Any idea?

——— apps.php

<?php
    $apps_list = array(
        'content', 
        'categories',
        'perch_blog',
        'perch_forms',
    );

my_form_for_later_php_include.php

<perch:form id="contacto" action="#" method="post" app="perch_forms">
    <perch:success show-form="true">
        <div class="enviado" id="ok">¡Mensaje enviado!</div>
    </perch:success>

    <div class="element-wrapper">
        <label>
            <perch:label for="input-nombre">
                <p>Nombre</p>
            </perch:label>
            <div><perch:input type="text" id="input-name" class="required" placeholder="Nombre" label="Nombre" /></div>
            <perch:error for="input-nombre" type="required">
                <p class="form-error">Por favor dinos tu nombre</p>
            </perch:error>
        </label>
    </div>
    <div class="element-wrapper">
        <label>
            <perch:label for="input-email">
                <p>E-mail</p>
            </perch:label>
            <div><perch:input type="text" id="input-email" class="required" placeholder="E-mail" label="email" /></div>
            <perch:error for="input-email" type="required">
                <p class="form-error">Por favor dinos tu correo electrónico</p>
            </perch:error>

        <perch:error for="input-mensaje" type="required">
            <p class="form-error">Por favor déjanos alguna nota</p>
        </perch:error>
        </label>

    </div>
    <div class="submit-wrapper">
        <perch:input type="submit" id="submit" value="Enviar" class="button submit-button-input" />
    </div>
</perch:form>
