Hyperlink on album thumbnails wrong

[kperson]

The hyperlink for the thumbnails for each of my albums is being generated in the form:
<servername>/coppermine/thumbnails-42.html
when it should be (I believe):
<servername>/coppermine/thumbnails.php?album=42.
The second form correctly brings up the thumbnail page for the desired album when manually entered on URL line.  The first doesn't since that html file doesn't exist.  This behavior began after I added a few hundred pictures last week, but I honestly can't say precisely when it started since I didn't try to use the albums until a couple of days later.  This behavior is happening with all albums -- I added a couple of new test albums to make sure.  I am on the road so don't have access to the server at the moment, but any ideas what would cause the hyperlinks for the album thumbnails to be generated incorrectly in this way?  Could I have changed some setting somewhere that caused this to start happening?  Thanks.

Yes, you have: turn the experimental SEF_URL plugin off.

Thanks, problem solved!  Now go get some sleep...
