The easy way: detele the style.css file on the widget folder.
If you’re interested on doing it by a plugin, you need to hook into the ‘ak_sideposts_style_url’ and return an empty string:
function disable_sideposts_styles( $url )
{
return '';
}
add_filer('ak_sideposts_style_url', 'disable_sidepost_styles');
Forgot that:
Another way to disable the styles is to create a file named ‘alkivia.ini’ in the wp-content folder with this content:
[sideposts]
disable-module-styles = On
thank you, that file alkivia.ini works perfect!
