[pmwiki-users] Problem with install in new system - PHP 7 ?

This function PCCF() most often registers the Markup rules that PmWiki 
will use to process the wikitext into HTML. Sometimes a typo in a markup 
rule will cause an error coming from these line numbers, even if the 
rules are defined in a recipe.

Do you have any recipes, skins or local configurations enabled on that 
wiki, or is it only the core PmWiki installation having the error?

If PmWiki without any configuration doesn't have the error, you can 
enable your recipes, one by one, and check every time if the error 
appears: you'll know that the last enabled recipe was responsible, and 
we'll help you fix it.

If PmWiki itself causes the error, I'll investigate it ASAP.
