Please note that there is an option in our Pro themes Customize section (for example Sydney Pro), which will allow you to change the footer credits very easily.
You can try to do the following in order to change your footer credits.
Go to your
public_html/wp-content/themes/ignis folder via FTP or cPanel, open
footer.php file with a text editor, and find this code:
<?php do_action( 'ignis_footer' ); ?>
…then replace it with something like that:
Changed text with desired text and/or link.
Also please note that you have to create a child theme and override modified
footer.php file in order to prevent your changes to be rewritten after theme update.
Kind Regards, Roman.
