First, double-check you have updated all core files, pmwiki.php and all
files in the scripts/ directory.
See also if in your cookbook and pub/skins directories you have the latest
recipes and skins that were published by their maintainers on
Next, in config.php disable all recipes: included files from the cookbook
directory, or a custom skin, or any line starting with "Markup(". You can
insert # at the beginning of a line to disable it.
Then test the wiki: if you have disabled everything, the warning message
Next, re-enable your customizations one after another, each time testing the
wiki. If at some point the warnings re-appear, you'll know that the
customization you just enabled is not compatible with PHP 5.5.
You can contact the authors of the broken recipes and (kindly) ask them to
update their recipes for PHP 5.5 - recent PmWiki versions add new helper
functions which make it easy. See http://pmwiki.org/CustomMarkup .
If you cannot have the recipes fixed by their authors, tell us and we'll try
to fix them.
Note that many hosting providers allow you to run different versions of PHP.
See the documentation of your hosting plan to learn how to enable a PHP
version earlier than 5.5.
Finally, it is possible to suppress these warnings in PHP 5.5, by setting
this line at the beginning of config.php:
error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
This will work, but should be a temporary solution, left only until your
recipes are fixed.
