php 7.1.0 to 7.1.3 breakage
From Wikistix
Upgrade broke MediaWiki 1.27.1, with the following traceback:
MediaWiki internal error.
Original exception: [WI2ZAMY2ckcAAXoh3UoAAAAr] /wiki/Main_Page MWException from line 1285 of /home/abc/w/includes/parser/Preprocessor_DOM.php: PPFrame_DOM::expand: Invalid parameter type

Thankfully, the fix is easy. Noticing that php dumped a bunch of warnings on startup:
$ php
PHP Warning: Module 'apcu' already loaded in Unknown on line 0
PHP Warning: Module 'curl' already loaded in Unknown on line 0
PHP Warning: Module 'dom' already loaded in Unknown on line 0
PHP Warning: Module 'iconv' already loaded in Unknown on line 0
PHP Warning: Module 'json' already loaded in Unknown on line 0
PHP Warning: Module 'mbstring' already loaded in Unknown on line 0
PHP Warning: Module 'pgsql' already loaded in Unknown on line 0
Edited php.ini to remove these extra unnecessary duplicate extensions, and bingo, MediaWiki was happy again.
