I tried K2 v2.0 with the free sig plugin but couldn't upload my pix. So after reading many posts I decided to buy Sig Pro 2 v2 because all problems would be solved with this one. Installed the plugin, set the folder to media/k2/galleries and selected my first zip with 5 pics in it (see picture k2_1). When hitting the apply button I get the message 'Changes to item saved'. Clicking again to see the details of the image gallery tab gives me following (see picture k2_2) and on the site I only get to see the title that there's an image gallery but nothing shows up see picture k2_3). The files got indeed uploaded to the server and none of the file names uses characters like - or _.
What could this be?????
