I'm getting this error:

Internal Server Error

Property "SurveyLanguageSetting.Array" is not defined.

An internal error occurred while the Web server was processing your request. Please contact the webmaster to report this problem.

Can anyone point me in the right direction as to where I can begin to diagnose this?

Start by

1. LimeSurvey version and build number
2. Hosting information
3. Debug mode manual.limesurvey.org/Debug_mode (maybe need to disable)

...and maybe some indication of what you were trying to do when the error occurred would be helpful.

Hi Denis,

Thanks for your response.

1) Version 2.05+ Build 150520, it's been running since 2013 with no issues however we just moved the server to a new host. Everything is working except the ability to update email templates.
2) InMotion Hosting. It's worked fine for us since 2013. We simply moved it from one account in InMotion to another just recently.
3) Ok, thanks.

Hi Tony,

So the issue happens when we are in the Admin panel. It happens with all the surveys so it isn't survey specific. When you go into "any" survey and then select the pencil icon and then "Email Templates" this is when the error occurs every time. It doesn't happen anywhere else. Please advise.

Thanks,
Rick

Really, really old version …

Maybe you have a broken survey : a surey without language settings.

We have 17 surveys. All the same error. It has to be a global setting or something else I am missing.

No , because in 2.05 : the top dropdown call all surveys.

Im sure you have debug mode activated …

Oh ok, I didn't check that. So is this what I should be checking:

Development and debugging
debug: With this setting, you set the PHP error reporting to E_ALL. This means that every little notice, warning or error related to the script is shown. This setting should be only switched to '1' if you are trying to debug the application for any reason. If you are a developer, switch it to '2'. Don't switch it to '1' or '2' in production since it might cause path disclosure. The default value is '0' and it can be edited in config.php.
debugsql: Activate this setting if you want to display all SQL queries executed for the script on the bottom of each page. Very useful for the optimization of the the number of queries. In order to activate it, change the default value to '1' from the config.php file.
In the case in which you experience an error in the application, we strongly recommend to activate the debug setting in order to get a more detailed error that you can submit with the bug report:

'config'=>array(
'debug'=>2,
'debugsql'=>0,
)
If you work on plugin and need a quick way to dump variables on screen : you can use traceVar function. If debug is set : this function use CWebLogRoute to be shown on HTML page. Usage traceVar($MyVariable)

This is the config file in application/config/config.php. It does not look like it is in debug mode.

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

Right,

And whan you activate : do you have more detail ?
Maybe the broken Survey id ?

Will the *.lss help provide this info?

No,

It's something in your database.

I think you have a survey without related language settings part.
