Hi, input an issue to github for that, but it seems that this was wrong: [https://github.com/mautic/mautic/issues/5802](https://github.com/mautic/mautic/issues/5802) Szenario: So my Use-Case was i copied an changed an existing theme (Blank, its great withe the Builder, but not realy responsiv), so in that workflow i create a version of myTheme upload it, create Content with the PageBuilder, tested it and some mistakes are in the HTML, so i improved myTheme, uploaded it an then the Problems came up Problem no Updating own Themes is possible without loosing of existing content. Solution Create a Button, update Theme which creates a new Mix of Theme+Content. Mayb be the Content must be stored, seperatly, like an xml-File. and the theme will be rendered with this content, like all php mvc-frameworks handel it, with php or twig. Upgrade solution use bootstrap3/4 as default, so layout elements are then container - to be defined rows - like section in combination with column columns - like section in combination with row elements - slots elements like text, image etc Layout Elements: Container, Rows, Columns with styling of position, floating, margin, padding, background color + image Content Elements: Text, Image, etc. with styling position, floating, margin, padding, background color + image, element specific properties So dropping table an change it to div for more responsivness. the structure is similar useds in clickfunnels. ---

+1 for this. The only reliable way to currently update a theme and have those updates apply to existing Pages/Emails that use it is to go directly into the database and update the HTML code. It’s stored in a DB column when you create the email and doesn’t update the theme TWIG HTML if it changes. A button that can force it to redo the HTML—or better yet auto-detect changes and auto-update in the DB would be superb. ---

+2 for this. An automatic DB update of the theme code if a newer version is detected would be awesome! ---

@Madlen I came across this old post in the ideas forum, and I think your theme switcher plugin which you demonstrated at the Mautic World Conference solves this problem, no? ---

Hi, This restriction used to be very important when we had the previous builder where all content blocks were template specific. In today’s builder we don’t have this restriction. The design won’t be broken. In fact the main function of the template is managing the unsubscription page. So the warning should be like “by chaging the template all template specific settings will be applied, like unsubscribe page and hardcoded design elements”. Joey ---

Thanks for the mention, Ruth. However, our bundle only works for emails with mjml (as of today).
