请问织梦自定义字段报错Call to a member function GetInnerText()

问题：自定义字段报错 Call to a member function GetInnerText() on string。
解决办法：
- 打开 /include/customfields.func.php 文件，将 $fvalue = trim($ntag->GetInnerText()); 改为：
```
$fvalue = ($ntag == "") ? trim($ntag) : trim($ntag->GetInnerText());
```
- 打开 /include/taglib/channel/img.lib.php 文件，将 $innerTmp = $arcTag->GetInnerText(); 改为：
```
$innerTmp = ($arcTag == "") ? trim($arcTag) : trim($arcTag->GetInnerText());
```
