Logging into the Magento Connect Manager, I've added the Extension Key from Magento Connect, and clicked "Install". For 0.2-0.5 Seconds, the "Please Wait" box flashes up then promptly disappears.
Nothing else happens at all. It happens whichever extension I try to install.
Very odd.
The store is v. 1.8.1.0 installed on CentOS
Could any body shine any light upon this at all, or suggest where I might look for more information.

It seems some of the files might be missing from the
downloaderfolder. Please copy thedownloaderfolder from the fresh magento1.8 folder structure and replace it on your website.Once done, check for the files and folder permissions. It should work for you. Please keep the backup of the old folder though.
