ERROR: Failed to create temp_dir with Enable Upload Progress Bar

[blackvault]

Hello,

I get the following error when trying to upload to the site after upgrading to 2.7:

ERROR: Failed to create temp_dir

I followed the instructions to activate the toolbar, and permissions on templates_c is 777. What is wrong?!

This can happen with wrong permission or wrong path set in ubr_upload.pl

Here are some of post in uber upload forum

What type of control panel you have on server.

If your server have connection rate limiting (to protect against dos) or load balancer, uber upload will not work.
