cannot open documents

I cannot open documents. The error message is "0 Call to a member function getObject() on null" but I don't understand that, either.

I have updated to 1.9.12 but the error still appears.

What should I do?

web page is dev.cactusact.org.au

I have set up a user called edocman with password vebmef-wobzap-7koCry

Hi,
Please try to go to Back-end -> Extensions -> Plugins and disable below plugins if they are available
- Edocman Dropbox
- Edocman Amazon S3
- Edocman Google Drive
Then, the issue will be solved
Thanks
