OPENTBS:FILE

Hello, I want to save a file on the server, but I always get an ERROR:

TinyButStrong Error OpenTBS Plugin: Method Flush() cannot overwrite the target file '/../test.odt'. This may not be a valid file path or the file may be locked by another process or because of a denied permission. The process is ending, unless you set NoErr property to true.

How can I fix that?

OpenTBS cannot replace the current template, because it is opened in read only.
