I’m using WP Discourse (2.4.8). Under the “Publihsing” tab, I uncheckedPublish the full post to Discourse, rather than an excerpt. Publishing posts works and an abbreviated representation is displayed in Discourse. However, when I update a post and select the Update Discourse topic function, the post does not update or submit the changes.
However, if I enable the Publish the full post to Discourse, rather than an excerpt. function, then updates also work, or the Update Discourse topic function works correctly.
I’m only posting from WordPress to Discourse. So yes, I am sure that I am saving the WordPress post first. Maybe it’s not happing with short texts. Could you try it with longer texts like 1500 words and more?
