Hey @der_velli,
Hope you’re well.
Can you change /wp-content/plugins/buddypress-activity-plus/lib/forms/link_tag_template.php content with this;
<?php
$target = in_array(BPFB_LINKS_TARGET, array('all', 'external')) ? 'target="_blank"' : '';
?><div class="bpfb_final_link">
<?php if ($image) { ?>
<div class="bpfb_link_preview_container">
<a href="<?php echo esc_url($url);?>" <?php echo $target; ?> ><img src="<?php echo esc_url($image); ?>" /></a>
</div>
<?php } ?>
<div class="bpfb_link_contents">
<div class="bpfb_link_preview_title"><a href="<?php echo esc_url($url);?>" <?php echo $target; ?> ><?php echo $title;?></a></div>
<div class="bpfb_link_preview_url">
<a href="<?php echo esc_url($url);?>" <?php echo $target; ?> ><?php echo $url;?></a>
</div>
<div class="bpfb_link_preview_body"><a href="<?php echo esc_url($url);?>" <?php echo $target; ?> ><?php echo $body;?></a></div>
</div>
</div>
It will make all elements as a link, I hope it can solve the issue. But this file changes will be deleted once the plugin updated so you need to do this again.
Cheers,
