Internal Error 500

[yaletech]

Hi,

I am having a small problem which I am unable to trace. Whenever I or anyone else click on a document link, an internal error is generated. I could still preview or download the document but was unable to figure out why the internal error keep coming up. Here is the internal error code.

An error has occured in the Share component: /share/service/components/comments/list.
It responded with a status of 500 - Internal Error.
Error Code Information: 500 - An error inside the HTTP server which prevented it from fulfilling the request.

The error come out when I used IE, Firefox and Chrome. Could someone figure out what I did wrong?

Thank you.

Each document has a list of comments below the preview.
Your error seems to be triggered while retrieving those comments so the preview works fine but the comments retrieving part is bugged.

I don't know where it comes from, but you should try tracing it with the javascript debugger (http://<yourserver>/alfresco/service/api/javascript/debugger)
