First, I must tell you, I am glad you develop this Plugin "Advanced code editor" and give it free for users. I use latest version very effectively, it makes fun to work in php-files and styles.css.
I use Theme Magazin Basic 2.7.3 with Plugin "Advanced code editor, last version" on a WordPress Site. Here the download of theme, styles.css ect. is possible, very easy.
Yesterday I had following problem:
I use updated Theme Magazin Basic 2.7.7 with Plugin "Advanced code editor, last version" on second WordPress Site. I can download single php-file and css-file without problem. But I can't download the theme. I see no reaction.
