Check Out Suddenly Stopped Working

I am running ZC 1.3.7 and I just got an email from a customer who couldn't check out. After looking into his issue I found that checkout has stopped working altogether! I haven't made any changes to the site other than upload an image. That is it and now the site doesn't work.

The checkout link can't seem to find the right filename! Here is what it looks for:

https://deadseamarket.com/index.php?main_page=FILENAME_CHECKOUT_LOGIN

That last part doesn't look right -- it should be this:

https://deadseamarket.com/index.php?main_page=checkout_login

I ran the PHP debug utility and got this:

[19-May-2009 14:50:23] PHP Warning: session_save_path() [<a href='function.session-save-path'>function.session-save-path</a>]: open_basedir restriction in effect. File(/home/coshla2/public_html/deadseamarket/cache) is not within the allowed path(s): (/var/www/vhosts/deadseamarket.com/httpdocs:/tmp) in /var/www/vhosts/deadseamarket.com/httpdocs/includes/functions/sessions.php on line 151

I am setting the site to maintenance mode for now -- anyone have any ideas????

What changes has your host made?

Kim,

I am not aware of any changes by my host though I have contacted them to at least set open_basedir to disable.

I do have a quick question. In what file is the 'checkout_login" filename defined? I can't seem to find it in my files for 1.3.7 -- maybe that file got deleted somehow....

Problem solved - my own idiocy. I accidentally moved a directory in an FTP rush. I found it and fixed it. Sorry for the bother.
