Problem changing header background

Hello,

I just installed WordPress on my site & added your free theme. Unfortunately, I seem to be having problems getting it to work right. I have selected the gradient option for the header, but when I try to change it to one of the other colours available, it will not change. Just remains on the purple. While that is a nice colour, it just isn’t what I want to use.

I had originally installed WordPress in a temporary directory as I used to have my site in Joomla, but decided to test out WordPress first. I was able to make the changes when I had it in the test site, but once I removed Joomla and installed WordPress in the main directory I have this issue with making the changes I wish to make.

Not sure how to correct this issue.
