我正在尝试使用php imap（）从收件箱中获取电子邮件。在localhost函数中工作正常但在我们基于bluehost的专用服务器上它显示以下错误

[an error occurred while processing this directive]

任何人都可以指导我在哪里可以解决的问题。我想要感激。谢谢。

EDITED 我向主机提供商添加了票证。以下是评论，

This error is because of a the FCGI timeout. This can be fixed by changing to suphp. You can change the php type in the whm to suphp on the Main >> Service Configuration >> Apache Configuration >> PHP and SuExec Configuration page. I suggest to closely watch the website with that to suphp as it makes the server more vulnerable to scripts running unchecked.
