I did a fresh install of Zenphoto 18.104.22.168 and just installed ZenPhotoPress plugin in my wordpress 3.4.1, on my ubuntu 12.04 server.
here you are the path :
In zenphotopress options I set the path to /home/user/zenphoto.wordpress.fr/zp-data
If i try to add photos in an article, by clicking zenphotopress icon, a pop up appears, and stay loading for some minutes after telling me that I have to configure the plugin options.
It seems that zenphotopress is looking for /home/user/zenphoto.wordpress.fr/zp-data/zp-config.php But there isn't such a file in Zenphoto 22.214.171.124 (been replaced by zenphoto.cfg).
Is that a Bug ? or is it my path that is incorrect ?
Anyway, this plugin seems very promising...I tried piwigomedia before, but never succed to get it work either, bad day :o)
