You may use the addon where you wish, but you will have to edit it accordingly.

Is there any template which lets me put an advert under the first post in a thread, on every page?

You may want to familiarize with the vBulletin template system a little bit more. :)

Sure it is. You may try with...

ad_showthread_firstpost_sig
ad_showthread_firstpost_start
ad_thread_first_post_content

... depending on what you would like to achieve. Don't be afraid to test things out! :)

Yes, I had already tried those and they didn't achieve what I wanted.

Then would you mind to mention an example?

Because I thought you wanted something like:

|-- showthread.php
|
|---- First post
|
|-------- [your ad here]
|
|---- Second post
|
|---- Third post

He wants it on every page, not just after the first post. I know it's possible because I have mine doing exactly this. And I'm sure I read how right here in this thread somewhere. Sorry I don't remember much about it. Try some searching?

Oh, I see. I missed that part. Sorry.

I want it how Videx has mentioned. However, even the above in your example - that would do for now, but I cannot achieve that either.

ad_showthread_firstpost_sig puts the banner in to the actual second post.
ad_showthread_firstpost_start puts the banner in to the first post.
ad_thread_first_post_content doesn't show the banner anywhere.

Okay, I found it here: https://vborg.vbsupport.ru/showpost....&postcount=722

Shows the ad after the first post on each page.

Hmmm... it looks like ad_showthread_firstpost doesn't exist on vBulletin 4.1.6 any longer. That's the version I've been working on today and that's why I didn't mention it in my reply.
