I had to resurrect a pmwiki when I updated from PHP 5.6 to PHP 7.2 on<br>
RHEL. The problems were entirely related to plugins or skins. Many<br>
required updating, but many of them in use were no longer currently<br>
maintained, so it ended up that they had to be fixed or removed. It<br>
wasn't easy to remove them, so fixing became the best option, and the<br>
patched files were uploaded to the relevant plugin pages on the<br>
PMWiki project wiki.<br>
<br>
There is no information given about what plugins or skins might have<br>
been in use, etc. It seems unlikely for help to be possible with so<br>
little effort given to providing information.<br>
<br>
Was a backup of the wiki made at any time? Providers like Softaculous<br>
offer backups being made before updates. Even if not made before an<br>
update, a backup made after would potentially allow for dropping<br>
the files on a local system or VM to debug if the web host does<br>
not allow shell access. Did you ask for shell access?<br>
<br>
Here are brief notes about the site I fixed:<br>
<br>
KB: 2018/12:<br>
<br>
The pmwiki site broke completely after upgrading from PHP 5.6 to PHP 7.2.<br>
The breakage appeared to be exclusively due to “Warning: preg_replace(): The<br>
/e modifier is no longer supported” issues.<br>
<br>
To address the issues, first, the site was upgraded to: pmwiki-2.2.110<br>
<br>
The triad skin was updated to the newest available at the time of the repair.<br>
<br>
Numerous cookbook files were either upgraded from the pmwiki site, or were<br>
locally patched. In most cases, locally patched files were uploaded to the<br>
pmwiki site (<a href="https://pmwiki.org/wiki/Cookbook/" rel="noreferrer" target="_blank">https://pmwiki.org/wiki/Cookbook/</a>) pages pertinent to the files<br>
that were edits, though in two cases, the pmwiki recipe pages were themselves<br>
affected by the preg_replace error, and changes could not be shared at the<br>
time they were made. The list of cookbook's modified:<br>

Naturally, your site will not be identical, but if you have things in the<br>
cookbook folder, probably they should be checked first and upgraded or<br>
edited as needed. When looking for upgrades, don't just download the<br>
plugin/skin tarball. Many plugins have individual files posted when a<br>
maintainer is not actively maintaining them.<br>
<br>
Other places for files that needed fixing were pub/* folders associated<br>
with plugins or skins, though for me, only handytoc put files there<br>
that needed changing.<br>
<br>
You should probably enabled diagnostics by uncommenting a line in the<br>
local/config.php file:<br>
<br>
# $EnableDiag = 1; # enable remote diagnostics<br>
<br>
There were only a few types of changes that had to be made. Provided that<br>
they turn out to be relevant, you could also look at how I changed the<br>
aforementioned files by examining what was uploaded to the plugin page<br>
and comparing it to the original published file.<br>
<br>
Good luck. Without more facts, actual help is hard to give.<br>
