Dear All
Here I got the advise to use Scary Transcluding to exchange content between wikis.
After a lot of confusion I understand now, that Extension:Interwiki will not make redundant to set "$wgEnableScaryTranscluding = true" in LocalSettings.php.
However, as soon as I set the command, my wiki will deliver an error screen with the following message:
Diese Seite funktioniert nicht localhost kann diese Anfrage momentan nicht verarbeiten. HTTP ERROR 500
Can you give me advise how to solve the problem or at least where to look for the cause?
Thank you in advance!
