1. IIS web.config
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<defaultDocument>
<files>
<clear />
<add value="index.php" />
</files>
</defaultDocument>
<rewrite>
<rules>
<clear />
<rule name="WordPress Rule" stopProcessing="true">
<match url=".*" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
<outboundRules>
<clear />
</outboundRules>
</rewrite>
<httpErrors errorMode="Detailed" />
<security>
<requestFiltering allowDoubleEscaping="true">

</requestFiltering>

</system.webServer>
</configuration>
errorMode，開啟log。
maxAllowedContentLength，增加file max size。
rewrite rules，參考wordpress官方文檔。
2. PHP temp folder permission
由於是wp-admin上傳檔案，所以要在temp folder allow permission。
