I've been able to install CB with Joomla 1.5.x previously but just completed a fresh installation using 1.6.0 and cannot get past the "There was an error uploading this file to the server" message.

* I've already verified the max limit size which is set to 10mb and all directory permissions are correct with Joomla showing green across the board. I can install templates and extensions with no problem, but not CB.

* Yes, I've downloaded the latest CB file and unzipped the file and get the error while trying to upload com_comprofiler.zip. The session isn't timing out either as it gives the error after approximately 10 seconds.

Thanks for any help you can offer!

I have the same problem.
It is my first attempt at hosting a site at greengeeks.com.
If it helps
Server info can be found here.

I was able to upload and install several more extensions without any problems as well. I tried downloading the entire CB file again and installed the login module without error but continue to get an error with the comprofiler...any help is greatly appreciated.

Still searching for a solution. I have compared the phpinfo file from two servers, one which joomla & cb have been successfully installed and one which joomla was installed but com_comprofile installation result the server error.
Possibly this information will help.

I am happy to provide access to cpanel if needed.
