This issue has been fixed in version 4.0.1. If you are using a earlier version of ignite gallery, and php 7.2 and have error reporting on full, you may get an error message that says:
Warning count(): Parameter must be an array or an object that implements Countable.
This can be fixed by upgrading to version 4.0.1, or by:
1): Lower error reporting: The error is a low level warning, it is usually not nescesary to output low level warnings. In the short term you can go to Joomla’s global config and set error reporting to minimum. This will still output important errors.
2) Or it can be fixed by editing:components\com_igallery\views\category\tmpl\default_main.php
