Ok,
To keep this forum from not resolved/unclosed topics, I thought it would be a good idea to clear things up.
The error “Creating default object from empty value in…” was caused by an impartial dbase. The dbase wasn’t for 100% imported to the new server/hoster, since it was just too big (400mb+) after asking the hoster to import it again but now on their server back-end, the error was gone and everything is fine now.
Thanks for your help.
