大家安装wordpress主题或者升级后发现如下错误，怎么解决呢？
Fatal error: Uncaught Error: Call to undefined function z_taxonomy_image_url() in J:\php\wordpress611\wordpress\wp-content\themes\home\header.php:111Stack trace:#0 J:\php\wordpress611\wordpress\wp-includes\template.php(783): require_once()#1 J:\php\wordpress611\wordpress\wp-includes\template.php(718): load_template('J:\\php\\wordpres...', true, Array)#2 J:\php\wordpress611\wordpress\wp-includes\general-template.php(48): locate_template(Array, true, true, Array)#3 J:\php\wordpress611\wordpress\wp-content\themes\home\index.php(5): get_header()#4 J:\php\wordpress611\wordpress\wp-includes\template-loader.php(106): include('J:\\php\\wordpres...')#5 J:\php\wordpress611\wordpress\wp-blog-header.php(19): require_once('J:\\php\\wordpres...')#6 J:\php\wordpress611\wordpress\index.php(17): require('J:\\php\\wordpres...')#7 {main} thrown in J:\php\wordpress611\wordpress\wp-content\themes\home\header.php on line 111
看提示是缺少一个函数，其实这是少了一个插件，插件名称叫【Categories Images】
后台搜索安装然后启用即可，如下图
然后模板一般会正常运行。
