Just tried the webdezine menu there are couples of issues
There is a missing close bracket at line 198, fixed, a step forward.
I put just `<?php
webdezine_list_cats();
?>` as a quick test and I got this
WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '->categories order by category_parent, cat_name' at line 1]
select category_parent, category_count, cat_name, cat_ID from $wpdb->categories order by category_parent, cat_name
By the way I put the require statement within body tag, guess this is OK. CSS required is appended to the existing CSS file so referencing is not a problem in my case.
In my template I have only this for a quick test
<div class="menucont">
<div class="topmenu">
<?php webdezine_list_cats(); ?>
</div>
</div>
Am I missing anything?
