Hi Jeanette,
I am sorry for the late reply. Can you turn on the error reporting to maximum and see what is the error generated.
By the way, you can always download the installer from
http://stackideas.com/dashboard and install it through Extension manager.
Please do remember that when you updating EasyBlog on your site, it is actually overriding all existing file with the latest. Please make sure that you have backup all your site's customization before continue update.
Please advise.
