Installation went ok except for 1 issue in that it could not import sample data, so I unticked that option and installation completed.
The rest of the installation went ok and the Shop appears fine in the web browser although as expected there is no sample data.

I tried to log in to the Admin Area without success. Username and Password is correct and made sure by editing the database and re-entering them.

Looking in the Apache Logs I get this :-

So, not sure what I am looking at here.

All the new versions of Apache/PHP/mySQL seem to perform correctly with each other otherwise.

Any Ideas?
