WP在标题页中出现错误

我会得到这个错误

Fatal error: Call to undefined function gdlr_print_header_social() in /home2/u9447441/public_html/wp-content/themes/clevercourse-v1-27/header.php on line 63

在第63行, 代码是这个

< ?php gdlr_print_header_social(); ?>

这是horder.php的全页代码

请帮助我我如何理解我不明白的东西
#1【WP在标题页中出现错误】只需删除该行和功能即可消除致命错误并显示页面。
不幸的是, 无论该函数是什么, 都没有在插件或你的functions.php文件中定义, 并且不会呈现。
如果你在文件中进行查找并替换gdlr_以重命名函数名称和类名称, 则可能需要对functions.php文件执行相同的操作。
