If your readers are having a hard time posting comments on your blog because they cannot continue typing the Word Verification code and the Post Comment button doesn't show up, here's the fix.
- In your Blogger dashboard, go to Layout > Edit HTML > Expand Widget Templates.
- Using Ctrl+F, search for data:post.commentFormIframeSrc. You will find the following code.
<iframe allowtransparency='true' expr:src='data:post.commentFormIframeSrc' frameborder='0' height='275' id='comment-editor' scrolling='no' width='438'/>
- Replace 'no' with 'yes' or 'auto' to enable auto scrolling and the comment form will automatically expand with or without a scroll bar.
