I installed Mautic on our own server and all works well so far, including a test email, but it uses the default content of the email. The reason is that when the email builder is loading, the builder button disappears with the opened builder being seemingly extended to cover the builder button / save button menu bar.
What can I do to keep the builder / save buttons not disappearing? I also managed to put a text-only version into its place and that seems to stay there after saving but the system does not copy the created text content into the theme version of the email. So the sent email still only shows the default content (“Hallo World, epsum…”)
