I bought and applied a new RWD theme called Ultimo to my 1.6.1 Magento store.
I followed the instructions and went into system > configuration and changed the package name to 'Ultimo' and the Theme setting to default.
After I did this I made sure I flushed the cache,cookies etc in Magento + Browser.
So when I go onto the customer side it still looks exactly as it did before the theme.
I have to manually go into each category or page and select Custom Design > Ultimo for any changes to appear.
This has ended up taking me a very long time, manually selecting the theme each time.
What are my options here?
