I'm trying to override the "vmpayment" plugin. I've changed the layout of the "post_payment.php" file and put the file in the following folder structure: templates/mytemplate/html/plg_vmpayment_standard_standard/post_payment.php
Now this is not working. The structure of the plugin is: plugins/vmpayment/standard/standard/post_payment.php
What am I missing here? I've changed it to exclude the last "standard" folder without success.
