Optimizepress is a theme that runs on WordPress, so if you have your site installed on WordPress and install the Optimziepress theme, it will override the look and feel of your site. Our theme does not affect your content (pages or posts) but it will affect the design and look of your pages, and remove any special features added by your previous theme
Think of a WordPress theme as a “skin” over your site.
Remember you can always switch back to your old theme as long as you don’t delete it in the Appearance > Themes section of WordPress
We have tutorials in the members area on how to install a separate version of WordPress in a subdirectory or subdomain of your site so that you can then run OptimizePress there and have no affect over your main site
