If you've ever spotted a bug in the source code of your Joomla site but can't for the life of you work out which file you need to edit in order to fix the bug then HD-Trigger is here to help!
HD-Trigger is a free plugin that simply replaces one snippet of rendered source code (the trigger) with your replacement code.
So simply copy and paste the buggy code snippet into the plugin and enter your ammended code to safely squash that bug.
Another benefit of HD-Trigger is that it doesn't modify the original source code - it simply amends it when it is rendered to the screen. This means you can safely run a Joomla update without fear that the edited files have been replaced.
