Physically, all files and DB data are still in place but for some reason the login page is not loading at all. Please help, how do I repair it?

OK ... what version of sugarcrm, php, database, webserver?

How long has it been installed ... did it install without problems ... have you ever had it running successfully?

[cedcas]

Here's the platform:

Apache 2.2.11
MySQL 5.1.30
PHP 5.2.9
SugarCRM CE 5.2.0j

It installed properly about 3 months ago and being use by about 5-6 users daily since then. The last time it was operational was when someone was modifying something in the dropdown editor through admin (yes, I don't get it too).

Have a look in the sugar.log ... see if you're generating any errors ...

Here are the last lines of sugarcrm.log, given that the whole app started to disappear on 11/5, nothing really out of the ordinary from the log pertains to it (log ended on 11/4):

Have you seen something like this before, where the whole application just disappeared? I also noticed that when I call /maintenance.php, it states "Down for Maintenance". Would this have anything to do with it?

Thanks and any help would be appreciated.

Found the cause of the problem by doing a process of elimination. The file en_us.lang.php located in /custom/include/language had been corrupted for some reason.

I also learned that this file contains all the added/modified dropdown field's options. Hence the last thing that the site admin did was modified the opportunities_sales_stage dropdown options

Whenever you get a blank screen in SugarCRM, your first step should be to turn display_errors or log_errors on on php.ini and check for php errors.

9/10 times this will show you instantly where this type of problem is.
The only reason SugarCRM ever renders an empty page is with php errors.
