We are using Service DeskManager 14.1. and SQL.
I can't upload a picture with the extension 'png' in the repository 'Images/pictures'.
Message: The type is not allowed. Change another file.
But this type 'png' is defined in options / attachments library / file type .
The files with the extensions (types) doc, xls or jpg can be loaded.
I checked also the file web.xml in bopcfg...... and found it.
What can be the cause?
