Hi, after a server migration i’ve the same problem indicated above
Fatal error: Call to undefined function phpadd_shortcode() in /home/hardstore/domains/applichiamoci.com/public_html/wp-content/themes/cian/sections/clients.php on line 1
Also with Cian theme enabled wp-admin access has this error too.
For now on http://www.applichiamoci.com you can see the old hosting without this issue.
Thanks
