500 (Internal Server Error) on MODx Manager Configuration tab

Hi there,

I have upgraded the from 1.0.5 to 1.0.13 and have been going through the site front-end and MODx manager and all seems well apart from one problem. I can access all sections in the Manager apart from the Site - Home tab and the Tools - Configuration tab. The pages tries to load and stops. I have checked the console log and am getting the error -

Failed to load resource: the server responded with a status of 500 (Internal Server Error) http://*****/manager/index.php?a=17
Refused to set unsafe header "Connection" index.php?a=1&f=menu:1
Refused to set unsafe header "Connection" mootools.js:2

I have also run this on a development server and all working well. Any ideas???

Windows NT WEBSERVER 5.2 build 3790 (Windows Server 2003 R2 Standard Edition Service Pack 2) i586
PHP - 5.3.6

I have now noticed the following error message appears but disappears when I click on the Configuration and Home tab

Array is currently editing these settings. Please wait until the other user has finished and try again

Regards,
Paraic

Thanks for getting back to me Garry. I did some poking around and had a look at the php page that contains the Configuration tab layout - (manager/actions/mutate_settings.dynamic.php). I uncommented the php code and the configuration form loaded. I started to remove the comments to see when the error would return again and I found that it happens around this line of code (line 32)

$lang_keys[$languagename] = get_lang_keys($file);

which is the language select box for the MODx Content Manager. I have checked the lang directory and all the files are there. The bottom line is I now have the Configuration tab but am unable to select a different MODx cms language which I wouldn't be changing anyway.

I'd still like to get to the bottom of it if possible.
