Right at the end even in the example alfabet.config file one can find the following line:
<add key="scan_templates_for_malware_when_publishing" value="false" />
Interestingly the Alfabets Administration Tools built in XML editor shows an error for this line and I am not able to find any hint within the administration manuals or code comments.
There seems to be no impact on the server so far but still an error never announces something good
Alfabet version is 10.9
