Topic on Extension talk:ContactPage

I just installed the extension on my wiki 1.39 but the wiki freezes.

Just followed the instructions,

If I remove the extension code from localsettings the wiki works again

Please respond asap

The infobox says ">= 1.42.0" so maybe it's not available for 1.39? On the other hand, there clearly is a branch for 1.39: https://github.com/wikimedia/mediawiki-extensions-ContactPage/tree/REL1_39
