[ic] Help, templates just disapeared

[Cameron Corda]

I've been working on my site a lot the past couple days, and I noticed a 
couple variables I had added to theme.cfg weren't appearing, so I 
updated the configuration in the admin UI.  I went to see the page to 
see if the variables were now working, and while they were translated, 
the templates (leftonly_top and leftonly_bottom) were not showing at 
all.  The html source only showed the content area, no template code 
anywhere.  I FTP'd into the site and all the template files were still 
there and contained the correct code, but aren't showing up in any page. 
 I tried deleting them and recreating them manually in the admin ui, and 
while the files would create they still won't show.  I reuploaded 
everything, and while they all appear as options for each page, 
selecting them doesn't make anything show up when the page is loaded. 
 Most of these templates havn't been edited in months, so it's not the 
info in the templates that is the problem.  It is as if after updating 
the catalog, some option turned off all templates, but I have no idea 
what I could have done to that.

Can anyone provide any insight as to what may have happened, and more 
importantly how to get them back.  The error logs have nothing 
interesting to show.
