I’ve got a couple of fresh installs of Magento 18.104.22.168 set up on our dedicated server but have run into a problem with Magento Connect.
When I check for upgrades all I get is a white screen with the following address:
http://www.[domain name goes here].co.uk/downloader/index.php?A=index&maintenance;=0&updates;=yes
Having gone through the code I’ve identified the page terminating in /downloader/Maged/Model/Connect.php at line 165 (by adding an exit(date(’r’)); line at the various points).
I will admit that I haven’t delved any deeper (into /downloader/Mages/Connect.php and further) but can do if helpful.
Does anyone know why this may be killing the page?
 - I forgot to mention I found the following thread which seems to have a similar problem but the workaround didn’t work for me.
