i have a strange problem. I run to multisite network, they

Hi guys, i have a strange problem.
I run to multisite network, they are the same, but hosted on different host (tsohost and siteground)

On the tsohost multisite network, with pro sites, i can import content from all my child themes with no problem.
On the siteground multisite network, with pro site (same setup as tsohost network) only parts of the content imports work.

Its is the same child themes, it is the data / content i try to import...

Only difference is that i and the support here have been trying to get the snapshot to work on siteground network...

What can i do to make sure but networks works 100%
