#1

i use dhtmlxVault 1.6 version. uploaded file size always smaller than 500M. But displayed following error.
error:
Undefined server error. Possible issues:

  • Unicode file name incorrectly processed by the server;
  • File size is bigger than server’s post-request limit (508M).

php.ini
upload_max_filesize = 500M
post_max_size = 508M
max_execution_time = 900
max_input_time = 900

What about the file name? Does it contain some special chars?

#3

file name is 02.jpg. When all file uploaded, displayed error. pls download dhtmlxVault 1.6 version. check it.

Try to debug the server script (UploadHandler.php). This error could be of different reasons starting from invalid php settings.
