Topic: pulling my hair out over this

two weeks ago i used i downloaded the very first simple viewer export for iphoto and it worked! none of the more recent versions have worked for some reason. I'm running OSX 10.4.4. I uploaded two galleries to:

http://disruptionlabs.com/iphoto_albums/

they worked great for two weeks. however now when i go to them the background color flashes and then I get a 404 and /upgrade.html is added to the directory target. I upgraded to flash 9 plugin about the time this problem started happening.  I changed line 14 in the flash detect file to point to version 9. doesn't make a difference. I even tried to create a gallery manually server side and get the follow error when trying to run the buildgallery script:

Warning: fopen(gallery.xml): failed to open stream: Permission denied in /home/cdouglas/disruptionlabs.com/photos/thewarehouse/buildgallery.php on line 115

Cannot open XML document: gallery.xml

Warning: fclose(): supplied argument is not a valid stream resource in /home/cdouglas/disruptionlabs.com/photos/thewarehouse/buildgallery.php on line 122

I'm not sure what to try next. Any insight would be excellent!

thanks!
