well… can you let me know what plugin you’re using? I’ll try and test it out. I think we did extra scrubbing on the new 2.1 version in dev but I’ll have to test. It evidently doesn’t work for every plugin.
Let me know and I’ll try and get some time to test.
The plugin is Live Blogging Plus (http://wordpress.org/plugins/live-blogging-plus/).
I’ve checked a bit more in detail and it seams not so much of a compatibility issue with this plugin (both, Live Blogging Plus and WP Facebook Open Graph Protocol are working together easily) or an issue with the Live Blogging plugin at all (except that it leaves the “post_title” empty). I first thought it puts the post_content in the post_title field, but it seams to be standar behaviour of WordPress to use the post_content as fallback it post_title is empty.
The issue seams to be that the Live Blogging plugin leaves the “post_title” and FB Open Graph Protocol (or even WordPress core itself?) seams to use the first x characters of “post_content” as fallback in case the title is empty.
As the Content usually atarts with an image (inserted via [caption ...] shortode), this shortcode goes into the Open Graph tag unfiltered.
Is there a way to simply (optional or always) strip shortcode from the content for use in the Open Graph tags? Or strip shortcode in case the content field is used as fallback for an empty title? Or something like this?
Have you tried using an SEO plugin to customize the titles? technically that could override the title and description auto-pulling body content.
Thanks, I’ll give it a try.
As for now, I’ve rolled back the Live Blogging Plugin to an earlier version where this issue doesn’t appear, though this might not be a long-term solution …
