Hi @anesioneto,
Yes it’s about the Target Self and Blank but it is not handled through CSS. You have to make changes on Html Code of the theme.
So to make the target “self” instead of “blank” please go to the header.php file of the theme and go to line no: 92. There you will fine the code as:
<a href="<?php echo esc_url( $newscard_settings['newscard_header_add_link'] ); ?>" class="newscard-ad-728-90" target="_blank">
Please replace the ‘_blank’ to ‘_self’ on it.
We recommended you to edit those code by creating a child theme so that your code won’t be lost while updating the theme to the new version.
Thanks
