OK, so I tried out Shashin in a multisite/multiuser test WordPress environment and was suitably impressed. Since I use Picasaweb a lot it was a terrific photo display solution. But when, together with the System Admin for my college, we migrated the WordPress code to a new server, somehow the plugin now fails to create a new album using a legitimate picasaweb album URL. This is certainly a local system problem since the same version of Shashin operates correctly on my sandbox site. What I'm not sure is where to look for hints as to what might be malfunctioning. Would there likely be an error message in the Apache error log? (not so likely I guess cos we're using nginx -- hahahahaha). I'm assured that the firewall is set to 'allow out' for web traffic, so it seems unlikely to be a firewall issue. Any thoughts?
Here's a URL FWIW : http://epress.earlham.edu/balkanicons/
