The page for showing topics, viewtopic_body.tpl contains the buttons that are displayed below posts. I call these “post buttons”. There’s a post button for ICQ, and in the default subSilver template there’s also a snippet for JavaScript code that shows a user’s ICQ online status by overlaying it with a green ICQ flower.
The same code is used in profile_view_body.tpl to display the user’s ICQ online status.
If you redesign this post button you may either have to remove or edit this code. It’s a simple piece of JavaScript so remove all the code between the <script>…</script> tags, remove the <noscript> and </noscript> and only keep the template variable placeholder for the image.
