Language file: Internal Server Error (Error 500)

Hi, 

I have deployed the FileVista Control application. On loading file manager interface , it gives the Error "There was a problem retrieving the language file: Internal Server Error (Error 500)". 

But from the web server itself, when we access as application (as locally) as http://localhost/ it works properly. Is this a known issue and any workaround available? Is there any settings need to be done with IIS? Due to this language file error, we were unable to move the system to production. Appreciate your help in this regard.

Problem Retrieving Language File

Hi Cem Alacayir,

Thank you for the response. Have tried the mentioned approaches and still does not working. The error message is as follows:

"There was a problem retrieving the language file: Internal Server Error (Error 500)".

It is running on IIS6.  Is there any other way to troubleshoot?

Thank you.

Best Regards,

If you open the Event Viewer, you should see the following message in the related error log:

Event code: 3005 
Event message: An unhandled exception has occurred. 
.

.
Exception information: 
   Exception type: InvalidOperationException 
   Exception message: Request format is unrecognized for URL unexpectedly ending in '/GetLanguageFile'. 


This means the following required setting in your web.config between <system.web> tags, is missing or not in effect:

        <webServices>
         <protocols>
           <add name="HttpPost"/>
         </protocols>
        </webServices>

Note that if you have separate web.config files in subfolders or subapplications, there may be some inheritance issue. You can try adding the required settings in all the web.config files including the root file.
