I wonder if anyone can help answer my question...
I'm looking for a CMS at the moment and I when I choose it I will spend a considerable amount of effort learning it, so I want to make sure I make a good choice.
My requirements are this:
I'd like to be able to install a theme and then be able to upgrade it without having other parts of the themes be incompatible with the latest version.
I'd like it to be secure, by secure I mean not prone to being hacked easily if the CMS software is kept up-to-date.
I'm not concerned with the CMS being easy to use as I will spend the time learning it. I tried Drupal and installed a theme/template and the shortly after I'd finished putting the site together (a lot of trial and error involved), a new version came out and parts of the theme I'd purchased were incompatible.
I'm looking for a CMS that I can keep up-to-date easily when a custom theme/template has been purchased then installed. I don't need a blog although it would be helpful and the rest of the site will just be your normal webpage type stuff - no ecommerce requirement or anything like that, just the ability to build a professional looking website.
My last attempt at a website was defaced so I'd like to go down the secure route this time and spend the time learning the CMS.
Thanks!

EDIT: I'd be keen to use either Drupal, joomla or wordpress as they seem to have the most themes/templates available for purchase but I am open to suggestions.
