Error message when trying to preview a word document in DekiWiki

[wonka]

I receive the following error message:
Loading Error:com.tf.common.security.TFAclManager For more information, please visit FAQ pages.

Is the Word document causing the error message or DekiWiki? How can resolve this?

I just noticed that DekiWiki doesn't show Excel and Word documents, none. It doesn't matter which file a select, DekiWiki keeps on giving the same error message.

I am using DekiWiki 1.9.0a on Ubuntu 7.10 server.

I've just updated to 1.9.0b and I still receive an error message no matter which Excel or Word file I want to preview on each page.

The error is generated by the ThinkFree viewer. It's possible that the document you're trying to view is not compatible.

Can you try to open the document at the bottom of the following page. Then we can eliminate your browser config to cause issues.

Just an idea, but could it be that the documents are password protected? Not sure if ThinkFree supports encrypted documents...

Hi merktnichts, no they're not protected documents. I've tested it today and now everything works. I don't understand why it works now, because I haven't changed anything to DekiWiki or the Word/Excel documents.

Perhaps the only thing that I can think of is a Firefox extension I updated yesterday. I haven't restarted Firefox until today, so the extension it active today. It's the GTDInbox extension (http://www.gtdgmail.com/).
