Very nice product but, out of the blue, it has stopped working and we lost the possibility to edit or recover the PlantUML code.

Hello and thanks for the heads up on this. It looks like Atlassian made a breaking change to Confluence. We've made an update on our end at everything is working again.

If it's still not working for you, please refresh the page or clear your browser cache. Once it's working for you, we'd appreciate it if you'd update your review to reflect this.
