Let me try to explain. There is a tool for Amazon affiliates, called Studio Publisher, that you highlight text or images with and it creates links using javascript instead of the traditional way of creating links. Is there anything in some of your themes that would prevent this from linking? I have no trouble with the Clean Retina theme but your other themes don’t pick up the links.
I’m also interested in this. I have the same problem. This CSS which you suggested will remove Next & Previous from the categories archive, search, etc. How can they be removed only from posts? Thanks
