Thank you for your earlier suggestion.
I have upgraded to 9.9.1 and have tried the following :
In Manage -> SItes, I added a new site with blank website as the Site Template.
Then I proceed to export from a site. It is still in submitted status.
I have tried the following link to resolve it, but it is still in 'submitted status'
So my question is, how else could I copy the same set of page templates from one site to another.
Would that be located in the Portals/ directory or would I have to modify the database?
Thanks very much.
