ox documents unable to open/create an excel sheet

[wesdgf]

Hi everybody,

since we have upgraded to Server-Version: 7.8.4-Rev21 on our UCS 4.2.3 Server, it's not possible to open or create an excel sheet anymore. The error code from the ox gui is:

Fehler

Beim Laden des Dokuments trat ein nicht behebbarer Fehler auf.
Error code: ERROR_WHILE_LOADING_DOCUMENT. File id: 1438/2632

Both word files and presentations working fine.

Is there a config file to check, or a logfile (which one?) to dig?

Cheers

Sebastian
