I was working on my site earlier today, No problem. The site has been up for years

I just tried to access the cataloge with a browser and it gives me a 404 error and http://my website/online/zc_install/index.php
The zc-install folder does not exist. I upgraded to 1.38 six months ago.

Also when I try to acess the admin I get
Warning: require(/home8/sub004/sc15698-NLZR/www/online/includes/autoload_func.php) [function.require]: failed to open stream: No such file or directory in /mounted-storage/home6a/sub004/sc15698-NLZR/www/online/admin/includes/application_top.php on line 147

Fatal error: require() [function.require]: Failed opening required '/home8/sub004/sc15698-NLZR/www/online/includes/autoload_func.php' (include_path='.:/usr/share/php5/') in /mounted-storage/home6a/sub004/sc15698-NLZR/www/online/admin/includes/application_top.php on line 147


I looked and my application top ends at line 131

ANY IDEAS
