Twitter malfunctioning in Preview mode.

I have the exact same problem.

Read more” class=”tw-share” title=”Tweet this post!”> appears to the left of the Twitter icon in published and preview.

Maybe someone else who is better at this can help, but I found removing

$twitter_meta = get_post_meta( $post->ID, 'gp_social_share_twitter-content', true );

in gp-social-settings.php fixes the issue. But at the same time, I do not know how to fix it without removing part of the code, which I assume is not a good idea.

For now, I have kept the code removed because it seems to be working perfect.

I have discovered it is because using the get_excerpt as the default content is pulling in the html including the read more button.

2.2 strips all html and read more from the default tweet
