As far as I can see, theme uses the_excerpt() tag. On the posts that were initially posted "as is", without using the <!--more--> tag, this theme gives me a link inviting to read more. So far so good. However, on the long posts that use the <!--more--> tag it doesn't give me a Read more link.
How do I go about getting the Read more link on the posts with <!--more--> tag?
Thank you beforehand!
