Have you changed any settings with your server recently?

Try disabling and clearing your cache.

I just noticed the error says "nvcsnew.org" The domain being used is nvcs.org

In your config/site.php file is the correct domain listed there or does it say nvcsnew.org?

The issue could be a form you recently created, if so, then you will need to delete the form by going directly to the DB using something like phpmyadmin, also check on your table "Logs" and see if you see any error/warning messages again using phpmyadmin.

If deleting the form directly in the DB does not work, try the steps below (on your root folder /home/nvcs_master/nvcsnew.org/) and let us know what happens:

1- rename your concrete folder to concreteOLD
2- upload a new concrete folder (just make sure it is the same version as you were running before)
3- try it again

I've made no changes to the site recently, no one has administration privileges but myself. I'll attempt the suggestions you have given so far. Thanks!

I just encountered the same problem on a site we run today:

Fatal error: Cannot use object of type ConfigValue as array in /home/altaprojects/imperialcountybicyclemasterplan.com/concrete/libraries/3rdparty/Zend/Cache/Backend/File.php on line 934

We haven't changed anything since this error was noticed (only 2 of us have access) and the only changes made recently were to take away a page from the auto nav.

I can access the DB from phpMyAdmin but I don't see any recent logs, nor do I know where I would delete any form.

I also tried to upload a new copy of the entire Concrete folder as suggested but received the same exact error (same line and all).

I've seen this error in various forum posts but none have helped so far. So any other ideas/assistance is welcome. Thanks!
