Hi Rikard,
Thank you for your reply. It does not really answer my question however I have managed to find the solution with my IT partner.
As for anyone also having this issue…
We needed to update the PHP version on the server first. After that the whole site crashes on PHP errors and than with FTP just rename(or delete if you’re brave enough) the old enfold folder in the wp-content->Theme folder to something like “old-enfold” after that throw in the new enfold folder and the website works again.
