I am trying to use the flash batch uploader in NextGen Gallery Version 1.7.4 without success. With each attempt I am getting error messages in the pop-up progress dialog box which are of the form:
ERROR HTTP ERROR : file1.jpg : 401
ERROR HTTP ERROR : file2.jpg : 401
ERROR HTTP ERROR : file3.jpg : 401
I am able successfully use WordPress' "built-in" flash uploader.
I've read a number of posts in the WP forums and elsewhere on the web suggesting (various) additions to .htaccess files as the solution. I have tried most or all of those .htaccess modifications and none of them have worked for me. Perhaps those mods are no longer valid?
Any help you can offer would be greatly appreciated.
