Thanks Petko,

Unfortunately, I had to travel to France in a hurry, but before leaving I had time to install php 5 back unto the server, and it works. When I'm back home, I'll try again with php7 and see if I can find the culprit amongst the recipes, the difficulty ebing that I use so many of them...

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.
