I want to add some content in footer file using VQMod my XML file has the following content but it's not working
<code>
<?xml version="1.0" encoding="UTF-8"?>
<modification>
<id>VQMOD CODE test data</id>
<version>1.0</version>
<vqmver>2.0.1</vqmver>
<author>authore name</author>
<file name="catalog/view/theme/default/template/common/footer.tpl">
<operation error="skip">
<search position="after"><![CDATA[
</footer>
]]></search>
<add><![CDATA[
this is test content
]]></add>
</operation>
</file>
</modification>
</code>
what is version of your opencart ?
it's dependent of your footer.tpl content. you need to make sure that </footer> is available in footer.tpl
and also you need to check in vqmod/logs you will see error log there.
