Fatal error: Call to undefined function get_custom_logo() in /home/u444363523/public_html/wp-content/themes/illdy/inc/back-compatible.php on line 7
Hello @hexacore,
This seems quote a strange issue but it seems like you might be missing a custom logo image in Dashboard > Appearances > Customize.
If nothing gets you forward, please consider to provide temporary admin dashboard access via a private post.
