Hi Robert,
We need to connect to the Joomshaper servers to make changes in excisting websites or isn't that required?
If I understand your question well, the answer is No. I mean you can create and edit existing pages/articles/modules created with SPPB even from localhost software without WiFi being on the remote island.
Access to JoomShaper server is needed only in two areas:
- When you want to preview & load Page Templates (Layout Bundles)
- When you want to preview & load Sections Library (Pre-made blocks)
Becuase they resources are loaded directly from JoomShaper WWW.
But custom saved Sections/addons are stored locally on your own www. And you can export & import pages from .json file.
