Your problem
My problem is:
Hi, I have a self-hosted mautic i ran which is active online. I have created a lot of email templates and landing pages for the mautic. However, I would like to be able to reupload or duplicate this mautic with the prebuilt templates so I don’t lose the landing pages or email templates I had made. Is there a way to do this?

These errors are showing in the log:

Steps I have tried to fix the problem:

You can clone the entire installation. That will bring the entire contact database over as well though. U could then delete out the contacts and create a “master” mautic. Then you would need to update your master ach time with each new template when made.

Not an ideal solution as I would want to deploy templates and campaigns to different Mautics on the fly.

The ability to export and import templates and campaigns would be an amazing feature. I am hoping the market place that is currently under beta, is a step in this direction.
