Answer 1

Add a reference to the jqgrid locale file first followed by jqrid

<script src="https://cdnjs.cloudflare.com/ajax/libs/jqgrid/4.6.0/js/i18n/grid.locale-en.js"></script>
<script src="https://cdn.jsdelivr.net/jqgrid/4.6.0/jquery.jqGrid.min.js"></script>

Answer 2

One get the error message typically if one don't included required language file grid.locale-XX.js (for example grid.locale-en.js) before jquery.jqGrid.min.js or jquery.jqGrid.src.js. See the example of the usage of jqGrid in the documentation.

Additionally I would recommend you to add gridview: true and autoencode: true option to jqGrid, remove non-existing myType: 'GET' (there are mtype option which default value if "GET"), reduce jsonReader to jsonReader: {repeatitems: false, id: "user_id"}, remove all index properties from colModel (because you use the values the same as the value of name property) and add key: true to definition of 'user_id' column.

Because you don't implemented server side paging of data I would recommend you add additionally loadonce: true option. It allows you to return all data at once from UsuariosGridData and jqGrid will implement client side sorting, paging or optionally filtering/searching of data.
