I have just downloaded your amazing theme and i'm testing it on my local backup. How can I use wordpress thumbnails of featured images in the excerpts? I'm trying but it seems doesn't work. In Settings>Media i have 150x150px for thumbs and they are normally in the upload folder, so Wordpress thumbnails are ok. In Atahualpa thumbs setting is 150x150 too and crop is enabled, but when i select a featured image, excerpts shows only the normal image with scale (for example, 150x114, or 114x150, etc). The url should be like image-150x150.jpg, instead it's just image.jpg (so, the normal image, with browser scaling for the excerpt).
What's the problem? How can I fix it? Thanks.
