Hello,
We have found this issue to be caused by WPmet plugins (ElementsKit or Metform) and is not something we can resolve in the exporter or faciliate fixing with WPMet. The advice we provide that seems to solve it is the following:
- Demo must be running PHP 8.0 or 8.1 (8.2 is problematic)
- All plugins should be at latest version
- Post Name permalinks must be set - avoid custom permalinks
- Only elementor/elementor pro can be network activated, Other addons are not designed for network and must be activated at site level,including the export plugin.
