Hi Axel…you obviously were not happy, but I’m still willing to help you set the theme so that you can use an excerpt instead of a content “read more” tag.
Themes in general displays blog posts in the home or archives in one of two ways, the first is using the_content() method which lets you insert a read more tag where you want it. The other is the_excerpt() method which will automatically create an excerpt of a certain length, or if you use a custom excerpt.
Themes are built with one or the other, but you can change that function from the_content to the_excerpt by overriding the theme’s template. Some themes will have the option to choose either one while many others do not offer that, whether free or premium. It’s not really a “standard” function for themes, but rather something a theme developer decides on.
Anyway, I can still help you change it to use excerpts instead if you wish?
