Hello
I got the same problem on search ,even with with custom images added in the no-thumb folder, template selected in Theme Panel -> Template Setting and Theme Panel -> Categories.
wp booster error:
td_api_base::mark_used_on_page : a component with the ID: thumbnail is not set.
/****/themes/Newspaper/includes/wp_booster/td_api.php
It went away after i added the bellow function in td_api.php after
/**
* the thumbs used by the theme
* Thumb id => array parameters. Wp booster only cuts if the option is set from theme panel
*/
and before the other td_api_thumb::add
Not sure is the correct way to fix it but it worked for me
td_api_thumb::add(‘thumbnail’,
array(
‘name’ => ‘thumbnail’,
‘width’ => 150,
‘height’ => 150,
‘crop’ => array(‘center’, ‘top’),
‘post_format_icon_size’ => ‘small’,
‘used_on’ => array(
‘MX2’, ‘Block 18’, ‘Block 19’, ‘Live search’, ‘tagDiv Image Gallery thumbs’
)
)
);
