Moving Prestashop and File Permission Errors

[robplugandplay]

Hello All,

 

I recently moved my prestashop to another domain and before I moved it the shop was working perfectly.

 

Now I have moved it however I am now getting the following error:

 

A file permissions error has occurred. Please check the permissions on the script and the directory it is in and try again.

 

I have altered the config files to reflect the new domain and database and I have chmoded my files giving directories 755 and files 644 and I still get this error.

 

Could someone explain to me please what files need what permissions?

 

Thanks in advance.
