The file is located at /modules/mod_easysocial_ads_showcase/tmpl/default.php

Feel free to make your own changes in that module

Post update of our Vanilla template, we no longer can access the custom.css section of that template where we previously made this change.

Do you want to address this bug so we can access our custom codes?

Temporarily, you could use FTP to make those changes

Yes, but there are a lot more custom.css codes we need, it saves us having to duplicate effort

This thread is about modifying the module and I don't see how it is related to your custom css.

To remove the navigational arrows:

1. Modify the file located at /modules/mod_easysocial_ads_showcase/tmpl/default.php
2. If you want to ensure that upgrades in the future don't mess up with your changes, create a template override in /templates/TEMPLATE/html/mod_easysocial_ads_showcase/default.php

You need to drop the attitude Mark, this is a paid service not a pro bono service. Your tone is not appreciated.

A separate ticket will be opened. We will not duplicate our efforts for a bug associated with your template.

Thanks! Likewise, it works both ways.
