It is likely that your hosting provider changed the PHP version (or you
changed providers), because there are no dramatic changes between 2.2.86
and 2.2.118.
This almost certainly comes from older recipes/addons or skin which
instruct pmwiki.php to perform a replacement that is no longer supported
by recent PHP versions.
See the page http://www.pmwiki.org/Troubleshooting
There can be different causes for page or page/section blanking, and for
the "deprecated" warnings, documented in that page.
How to find which addons cause the messages and the blanking of the
pages:
* disable all skins and addons,
* get the most recent version of every addon/recipe/module/skin you use
(read release notes),
* enable the addons one after another to see what works.
If you have any difficulty please report. We are in the process of
fixing all addons for PHP 7, if you need some that are not fixed we'll
do them first.

after an upgrade from 2.2.86 to 2.2.118, my PMwiki instance doesn't
show any content anymore in regular view. If I switch to edit mode, I
can still see the PMwiki notation of the content that should be there
but in view mode, I only see the sidebar, headers and footers but the
content area stays empty.
In the Apache error.log, I see many lines like this:
PHP Warning: preg_replace(): The /e modifier is no longer supported,
use preg_replace_callback instead in /var/www/pmwiki/pmwiki.php on
line 1790
What could I do to get the content visible again?
