[pmwiki-users] Problems with PmWiki & PHP 7.2

[Petko Yotov]

Both warnings you describe seem to be documented on this page:

    https://www.pmwiki.org/wiki/PmWiki/Troubleshooting

At donosborn.org/pmwiki/pmwiki.php?action=ruleset it appears that you 
have older versions of some recipes, specifically pagetoc.php and 
pmfeed.php (which have newer versions reportedly working with PHP7), nd 
rssdisplay.php (which may need an update).

The create_function() warning probably comes from multilanguage.php. 
I've uploaded a new version to the cookbook that should work fine with 
PHP 7.2, please get it there.

There may be other recipes that need updates for PHP 7.2, please read at 
the Troubleshooting page how to track those and report them so we'll fix 
them.
