verify_csrf throwing exception

When trying to save the "Filesystem path to your Gallery 2 embed.php file", I keep getting the error message below. I have tried both with Beta-1 as well as with the git master. This feature already worked for me in Alpha-4 btw.

Otherwise: great work, guys!

 So here's the error:
@todo FORBIDDEN

Hard to see how the csrf token could be missing there. I added a similar comment to the bug, too. Can you provide more details there please?

the problem seems to arise when attempting to import multisite g2 installs, see http://gallery.menalto.com/node/88169 and https://apps.sourceforge.net/trac/gallery/ticket/377

Hi,

I'm having the same problem and I'm also not using a multisite install.

So here's the error:

I deleted it from var/modules directory & now g2 import doesn't create a new var/modules/g2_import dir

I need to upload all directory and reinstall gallery3 or only /modules/g2_import?
