PowerCMS - Converting site to PHP from HTML
I have some websites that I created in Dreamweaver CS4 using both CSS and HTML templates. Every page was created using templates for consistency.
I want to use PowerCMS which does not appear to be working I believe due to not having PHP pages. Do I need to convert all my template created HTML pages to PHP? If so, what is the simplest way for me to do so and how would I convert my HTML templates?
Also, will I need to set up a testing server for this?
