This is the same bug that's already been fixed in www/mediawiki124 about a year ago. See bug 182710. I suspect it just needs applying to this port too. Fresh installation of www/mod_php56 and www/mediawiki123, using "pkg install" which also pulls in apache24 and php56 amongst others. Error message in apache logs: "Call to undefined function hash_hmac() in /usr/local/www/mediawiki/includes/specials/SpecialRunJobs.php on line 112." Fixed problem by: "pkg install php56-hash"
