But we have irregular unzip issues with it and 500 internal errors (maybe since joomla update?)
Really want this to work :(
As I stated in the Multi Install forum (http://forgetso.com/index.php?option=com_agora&task=topic&id=6&Itemid=3&p=3), the error you are seeing could be to do with folder permissions.
I pointed you in the direction of some helpful material on this subject matter, yet you have not responded with any indication as to whether you read it or not.
I also offered to take a look at your site but you didn't email your details.
