Automatic excerpts no longer work in WP 3.8:
I have the following option checked:
"Only use an excerpt of the post (AutoChimp will include a link back to the post). If you wrote an excerpt, that excerpt will be used. Otherwise, the first 50 words of the post will be used."
If a manual excerpt is added, the campaign pulls in the excerpt correctly, but if it is an automatic excerpt (should add first 50 words), it only shows ellipses (...) where the mc:edit="main" is placed.
I am using the most current version of AutoChimp. Has anyone else had the same problem or found a solution? I would really like to be able to use the automatic excerpt feature again...
