OK. I didn’t see : theme “UpStore” was updated.
I have to change something in the header-v4.php located in
/greennature/wp-content/themes/upstore/templates/headers/
<div class=”header-middle”>
<div class=”container”>
<div class=”logo-wrapper”><?php echo upstore_theme_logo(); ?></div>
<?php if( $theme_options[‘ts_enable_search’] ): ?>
<!– change search bar
<div class=”search-wrapper”><?php upstore_get_search_form_by_category(); ?></div>
–>
<div class=’search-wrapper’><?php echo do_shortcode(‘[wpdreams_ajaxsearchpro id=1]‘); ?></div>
<?php endif; ?>
<div class=”header-right”>
<?php if( $theme_options[‘ts_enable_tiny_shopping_cart’] ): ?>
<div class=”shopping-cart-wrapper”><?php echo upstore_tiny_cart(); ?></div>
<?php endif; ?>
</div>
</div>
</div>
it works now !
