A way of solving dokuwiki rendering issues

In this case , the rendering issues were caused, by having pcre2 @10.37_0 installed, so by just reverting to an earlier version, pcre2 @10.36_0, this solved the problem.

To show how this can be done on macOS, while using macports :

$ cd ~
$ git clone --single-branch https://github.com/macports/macports-ports.git
$ cd macports-ports
$ git checkout ed3c3a78664c989d2d06848e0d369b006af6a964
$ cd devel/pcre
$ sudo port install subport=pcre2

Once the installation done, do not forget to remove any Dokuwiki cache,

$ rm -r /var/www/site/data/cache/*

and this should solve rendering problems caused by having pcre2 @10.37_0 installed.
