I have seen this topic come up a couple of times before, but no one seems to have actually given a resolution for it.
I have a new WordPress site at http://www.thereign.net, and the Settings menu for "Reading" clearly shows "Full Text" as the option selected for the posts within my RSS Feed (http://www.thereign.net/feed/rss/). However, the feed does not give full text only the summary. I have tried selecting Summary and saving and then re-selecting Full Text and saving again, but this makes no difference whatsoever.
I have only two plugins enabled on the site; the built-in Akismet anti-spam plugin and the Odiogo text to speech plugin, which cannot possibly be the culprit since the whole point of that plugin is to take the Full Text from the RSS Feed and convert it to an audio file.
Problem is, if I cannot set the RSS Feed to use the Full Text option, then the audio files will only include the summary which generally amounts to around 20% of the post, rendering the audio feed useless.
If anyone has any ideas how to solve this, I would be extremely grateful.
