It can’t be a link without modifying the header.php template file. But as any changes will be over-written the next time you upgrade WordPress or the theme, it is recommended that you consider creating a child theme for your customisations.
Thanks a lot! I managed to create a child theme with another style.css file.
But this problem can be solved not with help of css. I guess I need to change the data in my database. Please,advise how to proceed!
You now need to create a modified header.php file in your child theme.
I modified header.php like this <div id="site-description"><a href="http://www.mysite.com"><?php bloginfo( 'description' ); ?></a></div>
It works both in main and in child theme. Now I need to copy the modified file to child theme catalogue?
Now I need to copy the modified file to child theme catalogue?
To the child theme folder? Yes.
Thank you very much, it works!
