카테고리에 전체  실족방지망 / 가압클램프 이런식으로 나오는데 

전체 카테고리를 안나오게 하고 싶은데 어떻게 수정해야할까요?

카테고리를 표시하고 있는 스킨 파일을 수정해주셔야 할 듯합니다.

FTP로 접속해서 /wp-content/plugins/kboard/skin/사용중인스킨/list-category-default.php 파일의 코드를

아래의 코드로 교체해보시겠어요?

<div class="kboard-category">
	<?php if($board->initCategory1()):?>
		<ul class="kboard-category-list">
			<li<?php if(!kboard_category1()):?> class="kboard-category-selected"<?php endif?>><a href="<?php echo $url->set('category1', '')->set('pageid', '1')->set('target', '')->set('keyword', '')->set('mod', 'list')->tostring()?>"><?php echo __('All', 'kboard')?></a></li>
			<?php $index = 0?>
			<?php while($board->hasNextCategory()):?>
			<li<?php if(kboard_category1() == $board->currentCategory()):?> class="kboard-category-selected"<?php endif?>><?php if($index):?>/ <?php endif?><a href="<?php echo $url->set('category1', $board->currentCategory())->set('pageid', '1')->set('target', '')->set('keyword', '')->set('mod', 'list')->toString()?>"><?php echo $board->currentCategory()?></a></li>
			<?php $index++?>
			<?php endwhile?>
		</ul>
	<?php endif?>
	
	<?php if($board->initCategory2()):?>
		<ul class="kboard-category-list">
			<li<?php if(!kboard_category2()):?> class="kboard-category-selected"<?php endif?>><a href="<?php echo $url->set('category2', '')->set('pageid', '1')->set('target', '')->set('keyword', '')->set('mod', 'list')->tostring()?>"><?php echo __('All', 'kboard')?></a></li>
			<?php $index = 0?>
			<?php while($board->hasNextCategory()):?>
			<li<?php if(kboard_category2() == $board->currentCategory()):?> class="kboard-category-selected"<?php endif?>><?php if($index):?>/ <?php endif?> <a href="<?php echo $url->set('category2', $board->currentCategory())->set('pageid', '1')->set('target', '')->set('keyword', '')->set('mod', 'list')->toString()?>"><?php echo $board->currentCategory()?></a></li>
			<?php $index++?>
			<?php endwhile?>
		</ul>
	<?php endif?>
</div>

고맙습니다.
