升级WP后如果出现类似如下错误：

Before you can upload your import file, you will need to fix the following error:

Unable to create directory /home/a3108847/public_html/wp-content/uploads/2011/04. Is its parent directory writable by the server?

解决办法：

WP后台–setting（设置）–Media(媒体）—Upload Files(上传文件）–Store upload in this folder(文件存储目录为）:

把路径设置为默认目录：wp-content/uploads
