The documentation suggests the following:
<?php if (in_category('3')) continue; ?>
Which will exclude a category from the index listing, but won’t that also hide the posts if the user is viewing category 3?
EDIT: By adding the following:
<?php if ($cat != 3 && in_category('3')) continue; ?>
My web comic will only show when its category is selected, however the front page of my blog now fails to show any post! I believe this is because I have my blog configured to only show 1 post per page. Any suggestions?
