My photo album has been working fine for several months but now when I try to Edit my album, I get the following error. Can someone tell me why this would start happening? Thanks.

Notice: class-album detected an invalid folder name: index.php?album=2011-03-india. in /usr/local/pem/vhosts/257266/webspace/httpdocs/zenphoto/zp-core/class-album.php on line 70 Notice: class-album detected an invalid folder name: index.php?album=2011-03-india. in /usr/local/pem/vhosts/257266/webspace/httpdocs/zenphoto/zp-core/class-album.php on line 70

Check the file/folder permissions, maybe your host changed something meanwhile.
Check if the album is actually in the /albums folder.

Btw, you did not tell what release, so we assume 1.4.1.3. If not you should upgrade.
