For any of you who may give Flatpress a try, there is a bug in the ReadMore plug-in. I have fixed it, and the corrected file is attached to this post. It should be placed in flatpress/fp-plugins/readmore/
To elucidate, the plug-in, as it was in the install archive, didn't reliably cut off text where I placed the
[more] tag. I rearranged a couple of if/then blocks within this particular plug-in file, and now it works reliably. Note that once you click the 'Read more...' link that is created by the placement of the
[more] tag, your post will no longer be truncated until you clear the Flatpress cache or else click on your Home widget.
You can see examples of the corrected plug-in in use
here, by taking note of the "Read more..." links at the bottom of truncated posts.
