CHMOD issue

Hi all,
I had migrated my website from a sub-domain to a domain ( TO
All seem working fine, but not for Permission CHMOD.

It seems that 755 isn’t working. So to allow a certain component to work I have to set up 777.
But before migration it had worked with 755.

I really can not understand what happenend?

Can you help me?

Thank you very much

PS: I forgot to say that it is a Joomla website

I agree - that doesn’t sound right at all.

Are both the domain and subbie under the same user?
