Website Joomla Core Customisations

The following Joomla! core files have been customised because there was no template override. The customisations need to be replied after every upgrade:

1. [joomla-root]/libraries/cms/helper/tags.php: Copy tags.org-v3.4.8.php over tags.php so that it replaces the content. This will ensure that additional columns for DPCalendar events are returned by the database query so that they can be displayed in any views that list thumbnails of articles with specific tags.
