[support] authorize.php problem?

[Warren Keuffel]

I'm running MAMP and VirtualHostX on my MacBook. I have a number of development sites set up that up until now have worked fine. Today when I tried to install a new theme or module after selecting the .gz file I get this URL and but then nothing happens (maybe WSOD?):

http://dev.git-test/authorize.php?batch=1&op=start&id=8

I created a fresh install of 7.15 and it all works fine. I can update modules and themes without problem.

The problem seems to be the authorize.php script. Any ideas on what I should do to make it work again?

Thanks.
Warren
