When a page containing tags and using the syntax (3rd party) plugin (though pages using other preprocessors may also be affected) is rendered as an inline page, some extra <p> elements are added.

Example output:

<p><span class="tags">
Tags:</p>

<p><span class="selflink">XML</span></p>

<p></span></p>

Expected output:

<p><span class="tags">
Tags:

<span class="selflink">XML</span>
</span></p>

A fix is to change inlinepage.tmpl to remove new lines around tag links, as follows:

--- templates/inlinepage.tmpl   (revision 4626)
+++ templates/inlinepage.tmpl   (working copy)

 <TMPL_IF NAME="TAGS">
 <span class="tags">

-<TMPL_VAR NAME=LINK>
-</TMPL_LOOP>
+<TMPL_LOOP NAME="TAGS"> <TMPL_VAR NAME=LINK></TMPL_LOOP>
 </span>
 </TMPL_IF>

I'm sure this is only working around a symptom, the problem must be that markdown gets confused by the html generated by the syntax plugin. Have you tried markdown 1.0.2? This version has a more robust html parser.

I don't have the prerequisites for the syntax plugin installed here to debug it myself. --Joey

I don't think that this is specific to the syntax (3rd party) plugin. It's happening on my pages that just use ordinary templates. I've documented my versions below. --?daveloyall

Can you show us the source code and output for a page that has this bug?

If you enable htmlbalance, does the problem go away? (If it does, then I think I might know what the bug is.) --smcv
