解决phpwind论坛附件上传的问题 HTTP error 412 [复制链接]

是主机安全设置的问题，解决方案如下：

The Precondition Failed error (code 412) is returned when a mod_security trigger is invoked. You can try creating an .htaccess file in your web root and adding the following lines in it:

SetEnvIfNoCase Content-Type \ "^multipart/form-data;" "MODSEC_NOPOSTBUFFERING=Do not buffer file uploads"

If the above code does not help, you can try these lines in the .htaccess file to completely disable mod_security:

<IfModule mod_security.c> SecFilterEngine Off SecFilterScanPOST Off </IfModule>
