If you’ve upgraded your Mautic to version 7.2.1 expecting the GrapesJS page builder plugin issue to be fixed, you’re not alone if it still refuses to load. A recent discussion on the Mautic community forum revealed users encountering the same frustrating message: “Please enable the GrapesJS builder plugin (or another builder plugin) to use this feature,” despite the plugin showing as enabled in the settings.
The culprit seems to be persistent even after performing a composer upgrade and clearing caches, which should have resolved the problem in theory. One user reported the GrapesJS plugin version stuck at 1.0.0, which is suspiciously low and might hint at installation or recognition issues within Mautic.
The forum poster also shared critical errors appearing in their logs, including an exception thrown by Twig related to an empty sequence mapping, which could be connected to this problem. Unfortunately, a quick search for related issues in the Mautic GitHub repository didn’t turn up any official bug reports or pending fixes at the moment, so this remains an open issue in the community.
What’s going on under the hood? GrapesJS is a cornerstone for building custom landing pages or email layouts visually in Mautic. If it’s not loading properly, it breaks a huge part of the marketing automation flow for those relying on the builder. The error message about enabling the plugin, combined with the plugin version oddity and the Twig templating error, suggests something deeper in how Mautic 7.2.1 currently handles plugin registration and template rendering—possibly still a work in progress or a hidden incompatibility with PHP 8.4 or MariaDB versions reported by users.
Until there’s an official patch or update, here are some practical thoughts:
- Double-check that the GrapesJS plugin is properly installed and enabled from the plugins page—sometimes toggling it off and on again helps.
- Clear caches thoroughly after upgrades, including manually deleting cache folders if needed.
- Keep an eye on Mautic’s GitHub and community forums for any official fixes or workaround scripts.
- Consider holding off on upgrade or testing in a staging environment if GrapesJS builder functionality is mission-critical for you.
This is a classic example of why self-hosted Mautic users sometimes face bumps with plugin dependencies after upgrades. Ran into this pain yourself? You’re not imagining it. For a hassle-free experience where you don’t have to chase these technical gremlins, Mailertizer offers a hosted Mautic platform with managed updates and tested plugins—letting you focus on marketing, not debugging.
