New to WP, but am am fairly experienced designer - and I've been messing with this for hours. Purchased a theme, uploaded it to the root www directory of my website (not a subfolder) under /wp-content/themes/forest. In the forest folder are the root files (index.html, contact.html, etc.) and the CSS files are housed under a presentation subdirectory. I looked in the presentation folder, and it shows several CSS files, one of which is styles.css. In the index.html for example the stylesheet link is "presentation/styles.css", so everything looks kosher.
I am getting a "the following themes are installed but incomplete" error and a "stylesheet is missing". But the stylesheet is not missing.
Any help would be greatly appreciated!!
