Allow me to open up this thread.
I was playing with the elpie code below, to try to solve the inconsistent "Continue to click" issue, re: WP's [...], and at first I thought it worked everywhere, but it doesn't.
Here are the conditions (note: when I refer to "Only Excerpts" that is a setting in ATO --> "Posts or Excerpts"):
1. If "Only Excerpts" is
not set and the <!--more--> tag
is used on a post, the elpie code below works.
2. If "Only Excerpts"
is set and the <!--more--> tag is
not used, the elpie code below works.
3. If "Only Excerpts"
is set and the <!--more--> tag
is used, the elpie code below does
not work. You get the excerpt but no tag.
4. If "Only Excerpts"
is set but an excerpt has been "hard coded" in Post Edit, even if you have the <!--more--> tag the elpie code below does
not work.
The moral of this story seems to be that you either use the elpie code below (or not) and consistently use the <!--more--> tag,
or you consistently "hard code" an excerpt for each Post (which, as I understand it, is preferable from an SEO perspective).
Hope this helps.
P.S. And maybe some day Flynn will whip out his magic keyboard, when he has some time, and develop a consistent solution for all occurrences of an excerpt.
