织梦自定义图片字段报错Call to a member function GetInnerText()

织梦程序当你添加了自定义图片字段时，前台打开当前栏目列表就会出现

Fatal error: Call to a member function GetInnerText() on string in /include/taglib/channel/img.lib.php on line 51  

后台出现

Fatal error: Call to a member function GetInnerText() on a non-object in /include/customfields.func.php on line 539  
解决方法

打开 /include/customfields.func.php 搜索

$fvalue = trim($ntag->GetInnerText());  

改成

$fvalue = ($ntag=="") ? trim($ntag) : trim($ntag->GetInnerText());  

继续打开 /include/taglib/channel/img.lib.php 搜索

$innerTmp = $arcTag->GetInnerText();  

改成

$innerTmp = ($arcTag=="") ? trim($arcTag) : trim($arcTag->GetInnerText());
