Ok, let's try to trace it down.

I have a clean installation and for me it works at any place for any placeholder, ranging from <!--@vbbanners:0@--> to <!--@vbbanners:9@-->. I do have also several production sites where it works perfectly well with any combination of rules, some of which are very complex.

Together, we have found that vbSEO may clean HTML comments, thus the standard placeholders won't work at all, and would have to be replaced by a different one.


(1)
In order to catch all possible errors, please make sure, your placeholder in the options looks like <!--@vbbanners:%d@--> or like @vbbanners:%d@ (if you have vbSEO or other software which cleans HTML). It may have any other combination of characters, as long as a %d appears inside. %d is replaced with numbers between 0 and 9 at runtime.


vbSEO or HTML cleaning software users:
vBulletin Options - Rotating Banner System Options - Nth Placeholder: @vbbanners:%d@

All other users:
vBulletin Options - Rotating Banner System Options - Nth Placeholder: <!--@vbbanners:%d@-->


(2)
Now put a:


vbSEO or HTML cleaning software users:
<div align="center">@vbbanners:0@</div>
<div align="center">@vbbanners:1@</div>

All other users:
<div align="center"><!--@vbbanners:0@--></div>
<div align="center"><!--@vbbanners:1@--></div>

in the template: ad_navbar_below


(3)
and enable the default banners, moving the second banner to position 1. Both banners should appear, one below the other.

On a standard installation, this combination of settings works 100% guaranteed on 4.0.2 PL1. I have set it up once again from scratch just to be sure. If it doesn't work for you, I'll install a test board with these settings on, in order to demonstrate the facts.


Possible issues:
- You are using a style which does not implement ad_navbar_below, or which comments out that template. In this case, no banner appears.
- Your system caches pages (e.g. Apache mod_cache). Unless you refresh the page explicitly, the banners don't seem to rotate or won't even appear.
- Your vBulletin Options - Rotating Banner System Options - Nth Placeholder is setup like: <!--@vbbanners:0@--> or @vbbanners:0@. In this case, only banners at location 0 appear. You should have set: <!--@vbbanners:%d@--> or @vbbanners:%d@ instead.
