How to adjust the sidebar width?

cannot put without the “//”, appear as

Parse error: syntax error, unexpected T_STRING in /home/zettaigl/public_html/princess/wp-content/themes/modularity-lite/functions.php on line 25

what is your file name archieve.php? or archive.php

File name should be archive.php

ok yeah sorry. that won’t help

//Add post thumbnail theme support
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 150, 150, true );

try this

is the right one “archive.php ”

Any others way can make it display properly?

Let’s first try it without the post thumbnail

in archive.php remove:<?php the_post_thumbnail(); ?>
in functions.php remove

// Add post thumbnail theme support
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 150, 150, true );

And see what happens

Do you have a category.php in your theme folder?

keesiemeijer:

i’ve try removed both of them, but the problem is still there…

only the thumbnail is not display but display full article.

i don’t have category under “theme” folder~

what can i do?is this the main causes?

file name would be archive.php and then follow the @keesiemeijer comment

i trying copy the theme from another website of me, which is working fine with the theme.

wat do u means by file name would be archive.php?

You can try this:
Duplicate your theme’s index.php and name it: category.php And look if the posts are shown.
