Can anybody tell me how to remove NextGen from my site comepletely so that I can re-install it? I tried to install the new version of NextGen Gallery [1.5.3] and all my portfolios disappeared from my site. I tried a couple more times and I kept getting the following error message:
Downloading install package from http://downloads.wordpress.org/plugin/nextgen-gallery.zip.
Unpacking the package.
