Invalid security token on post

[vdonadio]

Hi all,

I created a carrier module, it's not my first one. In the configuration page, I have a form with many fields, it's actually really basic

Configure.tpl

<script src="/modules/pickit/views/js/back.js"></script>

<section class="clearfix">
	<div class="row decidir-header">
		<div class="col-xs-6 col-md-4 text-center">
			<h4>Credenciales de proveedores</h4>
		</div>
	</div>

	<hr />
	
	<div class="pickit-content">
		<div class="row">
			<div class="form-group">
				<div class="col-md-2">
					<label>Proveedor</label>
				</div>
				
				<div class="col-md-3">
					<label>API KEY: </label>
				</div>
				
				<div class="col-md-3">
					<label>TOKEN: </label>
				</div>
				
				<div class="col-md-3">
					<label>URL Servicios: </label>
				</div>
			</div>
			<form action='' method='post'>
			{foreach from=$suppliers item=supplier}
				<div class="form-group">
					<label class="col-md-2">
						{$supplier.name}
					</label>
					
					<label class="col-md-3">
						<input type='text' name='api_key[{$supplier.id_supplier}]' id='api_key_{$supplier.id_supplier}' class='mdl-textfield__input' value="{if 'credentials'|array_key_exists:$supplier}{$supplier.credentials.api_key}{/if}"/>
					</label>
					
					<label class="col-md-3">
						<input type='text' name='token[{$supplier.id_supplier}]' id='token_{$supplier.id_supplier}' class='mdl-textfield__input' value="{if 'credentials'|array_key_exists:$supplier}{$supplier.credentials.token}{/if}"/>
					</label>
					
					<label class="col-md-3">
						<input type='text' name='webservice_url[{$supplier.id_supplier}]' id='webservice_url_{$supplier.id_supplier}' class='mdl-textfield__input' value="{if 'credentials'|array_key_exists:$supplier}{$supplier.credentials.webservice_url}{/if}"/>
					</label>
				</div>
			{/foreach}
				<input type='hidden' name='saveCredentials' value='1'/>
				<label class="col-md-2">
					<input type='submit' class='btn tbn-flat btn-info' value="Guaradar"/>
				</label>
			</form>
		</div>

		<hr />
		
		<div class="row">
			<div class="col-md-12">
				<div class="row">
				</div>
			</div>
		</div>
	</div>
</section>

 

When I get into this configuration page, everithing works fine, but when I click on submit, I get the error of "Invalid security token"
The funny thing is that, as you can see, I'm posting to the same page where I am - Which is catched by an admin controller inside this module. Same parameters, same token.

Any ideas? I'm really stucked

Prestashop 1.6.1.4

Where in your form is the token?
