How to remove category title

edit category.php (if there is none, then edit archive.php; if this is not there either, then edit index.php)

look for a line of code with single_cat_title(); – then delete it with the corresponding html tag.

make a backup copy of your theme files before editing.

I found these codes in archieve.php just like following;

if (have_posts()){

global $posts;
$post = $posts[0];

ob_start();

if (is_category()) {

echo ‘<h4>’. single_cat_title( ”, false ) . ‘</h4>’;
echo category_description();

} elseif( is_tag() ) {

echo ‘<h4>’. single_tag_title(”, false) . ‘</h4>’;

} elseif( is_day() ) {

echo ‘<h4>’. sprintf(__(‘Daily Archives: <span>%s</span>’, THEME_NS), get_the_date()) . ‘</h4>’;

} elseif( is_month() ) {

echo ‘<h4>’. sprintf(__(‘Monthly Archives: <span>%s</span>’, THEME_NS), get_the_date(‘F Y’)) . ‘</h4>’;

} elseif( is_year() ) {

echo ‘<h4>’. sprintf(__(‘Yearly Archives: <span>%s</span>’, THEME_NS), get_the_date(‘Y’)) . ‘</h4>’;

} elseif( is_author() )

But i don’t know where I need to make changes

Remove or comment out

echo '<h4>'. single_cat_title( '', false ) . '</h4>';
echo category_description();

(To comment them out, and thereby leave the code in the file in case you need it later, just add // before each of those two lines).

As alchymyth said- do back up before you make any changes.

And see if that does what you need.

problem solved ??
thank you so much Joshuwar and alchymyth
