Hello everyone

Got this error message in Odoo: 

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

I had updated a file and was upgrading the module when I got this error:

ParseError: "ValidateError

Field(s) `arch` failed against a constraint: Invalid view definition

Error details:

Field `labels_id` does not exist

Error context:

View `vetclinic.animal.form.view`

[view_id: 643, xml_id: n/a, model: vetclinic.animal, parent_id: n/a]" while parsing file:///C:/Odoo/server/openerp/addons/devTrain/devtrain_view.xml:16, near

<record id="vetclinic_animal_form_view" model="ir.ui.view">

<field name="name">vetclinic.animal.form.view</field>

<field name="view_type">form</field>

<field name="model">vetclinic.animal</field>

<field name="arch" type="xml">

<form string="Animal">

<field name="name"/>

<field name="birthdate"/>

<field name="breed_id"/>

<field name="classification_id"/>

<field name="labels_id"/>

</form>

</field>

</record>

When I clicked "OK" I got internal server error and now I can't get back into Odoo. I tried stop/start on both Odoo and Postgre server but still nothing. This has happened twice today (on my local and my remote machine). 

Can anyone help me?
