showBasketLink plugin not found

I’ve installed a theme from Githib that the archivists wanted to try and it seemed to install fine. However when they try to view images they get the error:
A plugin by the name showBasketLink was not found in the plugin manager Zend\View\PluginManager

I’ve done some searching online and I can’t find anyplace to get this plugin. Is anyone familiar with it?


This is probably a bug (of course).

Check the file in the theme where the issue occurs, and remove it or check it before.

<?php if ($this->getHelperPluginManager()->has('showBasketLink')) echo $this->showBasketLink(); ?>

Check if the theme was not updated before (if this is the theme “psl”, there is a full update on my github account, but it is not yet merged on the upstream version).
