Cant be a memory thing as its a clean install! Nothing been done to the script apart from a template (after the issue).
Not getting anywhere at the moment, had 7 different support team dealing with one ticket over 2 days. Something makes me think Im dealing with a call centre and not a 'team' who know the host and software...

Either way, Ive been told that changes have had to be made to the softaculous install to get things working. Even though they still are not!...
