[Hippy]

in your post_thanks_postbit_info template youll see this 3 time

{vb:raw post.post_thanks_thanked_posts_formatted}}</dd>

try adding a <br /> after each

if that does not work try
replace the template with

<vb:if condition="$post['userid']">
    <dt>{vb:rawphrase post_thanks_thanks}</dt> <dd>{vb:raw post.post_thanks_user_amount_formatted}</dd>
    <vb:if condition="$post['post_thanks_thanked_times'] == 1">
        <dd>{vb:rawphrase post_thanks_time_post}</dd>
    <vb:elseif condition="$post['post_thanks_thanked_posts'] == 1" />
        <dd>{vb:rawphrase post_thanks_times_post, {vb:raw post.post_thanks_thanked_times_formatted}}</dd>
    <vb:else />
        <dd>{vb:rawphrase post_thanks_times_posts, {vb:raw post.post_thanks_thanked_times_formatted}, {vb:raw post.post_thanks_thanked_posts_formatted}}</dd>
    </vb:if>
</vb:if>

I would have to test it out tomorrow if either does not work..

if they fail revert the template back ..

let me know how you make out
