## 症状

Below are some symptoms you may encounter, not necessarily all inclusive:

1. When editing an attachment using the Office Connector, you may see an error message like below:

"The Internet Address ... is not valid"

2. Alternatively, you may see a blank document despite that the attachment is a valid attachment.
3. When observing the HTTP traffic (eg. via Fiddler), you may encounter a 404 error. Indicating the path to the attachment file is a wrong path.

## 原因

The Office Connector plugin is reading paths from the Confluence Ancestor table, which can get corrupted. The root cause for this corruption is still under investigation: 'The Internet Address ... Is Not Valid' Error Message Due to Corrupt Ancestor Table.

## ソリューション

1. Rebuild the Ancestor table to correct the issue. Note that in some instances, this action can take a long time to complete.
2. From Administration >> WebDav Configuration, check the box labeled "Disable strict path check". This is available from WebDav version 2.1 onwards. See related improvement request: WBDV-204
