When I activated a IIIdyl theme I got this message: ‘Fatal error: Call to undefined function get_custom_logo() in /home/website/public_html/wp-content/themes/illdy/inc/back-compatible.php on line 7’. Now my whole website and worse, my login page has this error message so I can’t even log in anymore. PLEASE HELP PLEASE! I am new to this!
Hello there,
I am sorry for the inconvenience caused here.
Since you are unable to login, you will have to contact your hosting provider and have them disable or delete the theme and ensure that WordPress has been updated to the most current state. This issue can occur when WordPress is out dated.
Best Regards,
Support
