Your plugin’s css has 50px of padding on the left which is why it appears cut off on the right, since its being pushed over. You can override that css by adding this to your style.css file –
#social .social-comment-body {
width: auto !important;
}
For the second question please create a separate thread/topic. We have a “One Question Per Thread” policy, that we all have to follow (including myself). This helps us keep everything organized, and it makes it easy when other users are searching for similar questions.
Let me know if the above code fixes the comment issue.
Thanks
