Thank you for pointing these things out. You should be able to correct the issue with adding/removing entries from your favorites by looking in your 'ADV_DYNA_SHOWENTRY' template for this code:
<li>
<vb:if condition="$entry['isfavorite']">
<a onclick="vba_add_fav({vb:raw entry.entryid});" href="misc.php?{vb:raw session.sessionurl}do=removefav&e={vb:raw entry.entryid}&return=entry{vb:raw adv_sorturl}"><span id="fav_{vb:raw entry.entryid}">{vb:rawphrase remove_from_favorites}</span></a>
<vb:else />
<a onclick="vba_add_fav({vb:raw entry.entryid});" href="misc.php?{vb:raw session.sessionurl}do=addfav&e={vb:raw entry.entryid}&return=entry{vb:raw adv_sorturl}"><span id="fav_{vb:raw entry.entryid}">{vb:rawphrase add_to_favorites}</span></a>
</vb:if>
</li>
And replacing it with this:
<li>
<vb:if condition="$entry['isfavorite']">
<a onclick="vba_add_fav({vb:raw entry.entryid});" href="javascript://"><span id="fav_{vb:raw entry.entryid}">{vb:rawphrase remove_from_favorites}</span></a>
<vb:else />
<a onclick="vba_add_fav({vb:raw entry.entryid});" href="javascript://"><span id="fav_{vb:raw entry.entryid}">{vb:rawphrase add_to_favorites}</span></a>
</vb:if>
</li>
To correct the issue with the New Posts link in your Quick Navigation module, you will need to look in your {vb}/vba_dyna_modules/dyna_navigation.php file for this line:
$templater->register('newpostlink', $newpostlink);
And replace with this:
$templater->register('newpostslink', $newpostslink);
Then you will want to replace the contents of your 'adv_dyna_module_quicknav' template with the follwing code:
<div class="blockrow">
{vb:raw quicknav_toplinks}
