Hello,
Thanks for using my plugin.
Unfortunately you can’t do that unless by editing the core plugin file.
Use the FTP program to go to wp-content/plugin/twb-woocommerce-reviews folder and edit the file ‘twb-output.php’.
On line 154
replace this code echo'<div class="twb_wcr_author">' .get_comment_author($twb_wc_review). '</div>';
with following:
echo'<div class="twb_wcr_author">' .strtok(get_comment_author($twb_wc_review),' '). '</div>';
Save the file and that should do the work.
Please remember when in future if there’s a plugin update, this change will override.
If any issue, let me know.
Thanks
Abu
