A 500 error occurred when uploading videos through SWFUpload.

When a 500 error occurs during SWFUpload video uploading, I use swfupload to upload a video with the 500 error. what is the problem? Asking for advice? & Nbsp; on the index. php page, I changed file_size_limit: & quot; 200 MB & quot;, & nbsp; SWFUpload to upload a video with a 500 error.
Why is the error 500 returned when I upload a video using swfupload? Asking for advice?
On the index. php page, I changed file_size_limit: "200 MB ",
File_types: "*. *", error 500 occurs when uploading a MB video.

And I'm in upload. on the php page, $ extension_whitelist = array ("doc", "txt", "jpg", "gif", "docx", "png", "wmv", "rmvb ", "flv"); // allowed files to be uploaded


If the path is not Chinese, why is the error 500 in English?

------ Solution --------------------
Check whether you have the permission. In addition, the maximum upload size is 2 MB by default. you need to modify the upload size limit in php. ini.
