问题关键在函数 updateThemeConfigMore($configMore, $moreInDb); 如果json文件有语法错误，$configMore没有正确读取。可能造成配置丢失。
在函数updateThemeConfigMore开头加如下代码输出json生成的数组
echo empty($configMore)."
";
print_r($configMore);
return;
模板更新，当json文件有语法错误（如少一个逗号）时，$configMore的值是空数组，empty($configMore)值返回1。
themes/w0s/portal/index
1
Array

解决方案 updateThemeFiles函数里增加对json转换结果的判断，转换成功再更新数据库。
