I try to fix by myself, but no result. 我尝试自己修复,但没有结果。 Please help me, really appreciate for any help.
请帮助我,非常感谢您的帮助。

This error is because the global object global $up_options
is not defined. 该错误是因为
global $up_options
全局对象global $up_options
。
Try to var_dump $up_options
, it might be null. 尝试
var_dump $up_options
,它可能为null。
Also check if you have spelled the variable name correctly. 还要检查您是否正确拼写了变量名。
Run this code, and check the output: 运行以下代码,并检查输出:
function upfw_setup_theme_options(){
$up_options_db = get_option('up_themes_'.UPTHEMES_SHORT_NAME);
global $up_options;
$up_options = new stdClass();
//Check if options are stored properly
if( isset($up_options_db) && is_array($up_options_db) ):
//Check array to an object
foreach ($up_options_db as $k => $v) {
$up_options -> {$k} = $v;
}
else:
do_action('upfw_theme_activation');
endif;
}
add_action('upfw_theme_init','upfw_setup_theme_options');
add_action('upfw_admin_init','upfw_setup_theme_options');
