If you recently upgraded your Mautic installation to version 7.2.1 hoping it would fix the stubborn GrapesJS builder plugin loading issues, you’re not alone in running into trouble. Several users in the community have reported that despite upgrading, GrapesJS still fails to load, showing the frustrating message: “Please enable the GrapesJS builder plugin (or another builder plugin) to use this feature.”
The story goes like this: you perform your usual composer upgrade, clear caches as recommended, confirm the plugin is enabled on the Plugins page, but the quirky error remains. Interestingly, some users see the plugin version stuck at 1.0.0, even though it should be further along — a hint that the update process might not be fully registering the plugin.
What’s complicating matters is a reported error involving Twig templates, specifically something about a missing key in a chart-related twig file. While this does not directly scream GrapesJS, it signals there might be underlying templating or plugin registration issues related to the upgrade.
We tried scouring GitHub for an official bug fix or patch related to this problem for 7.2.1, but no clear solution or open issue is showing up prominently. It looks like this is a bug still gaining traction among devs and the community. Your best bet right now is to watch the Mautic GitHub repo and community forums for updates.
What does this mean for you if you rely on GrapesJS? Patience, mostly. Upgrading Mautic doesn’t automatically fix this glitch yet, so you may want to hold off on updating if your campaign builder depends on GrapesJS, or keep a close eye on any development. Meanwhile, clearing caches, double-checking plugin toggles, and verifying your composer install logs are clean won’t hurt, though it sadly might not be a magic bullet at this time.
In short, this issue is a classic “not quite fixed yet” upgrade hiccup. For marketers and admins who need seamless page or email design tooling, this can be a real snag. If you’re not into troubleshooting plugin woes or waiting on patches, platforms like Mailertizer handle all this backend complexity for you so you can focus on your marketing, not debugging.
