Thread:Extension talk:ContactPage/'IncludeIP'= is missing/reply

That's strange. On my test wiki 1.23.5 I am using version 2.2 and when omitting the line for  as in the example on this extension's page everything works fine.

The story is a bit more verbose when looking at the server's error log: You indeed get PHP notices but only if you include this line either with "true" or "false". I reported this with 65063 and still hope that it gets fixed one day.

However since this option is part of an wider array it should probably be displayed on the extensions page for better user guidance. I will add it.

Cheers
