Graham tiaxgame I did this for ah.sdq
you convert the data for the url into an array split at the ? and then use the first part as the url for the link
for the links in the post list
this creates the array
{% set url_no_query=entry.url|split('?') %}
then you use it like this
<a class="xt_blog_title_link" href="{{ url_no_query[0] }}">

you need to do the same for tag urls
