# The Events Calendar 5.4.0.1

### Summary

Hotfix Release

This hotfix version of The Events Calendar includes a fix to prevent a fatal on PHP 5.6

This is a hotfix release, meaning that it’s focused on fixing a specific bug only.

As always, we recommend updating on a [staging site](https://docs.nexcess.com/software/the-events-calendar/creating-and-using-a-wordpress-staging-site/), just to be safe, but it should all be smooth sailing.

#### ✅ Fixed

Bugs that were squashed in this release

- If your site is on PHP 5.6, under certain scenarios you’d get a fatal when editing a post or page that uses some of our widgets. We made sure to fix that.
