I run one PmWiki, just because someone else set it up. So I haven't dug too much into it, but the more I do, the more I like it. It's pretty scrappy, but very customisable. I guess similar reasons to why I like Textpattern, but maybe even more-so.

I dunno, here're a bunch of links:

• https://www.pmwiki.org/wiki/Category/WikipediaSuite
  I've been looking at PmWiki again as an alternative to MediaWIki, mostly because MW is kinda a mess in ways I don't like, and the search is garbo.
• https://www.pmwiki.org/wiki/PmWiki/CustomMarkup
• https://www.pmwiki.org/wiki/Cookbook/Cookbook
  Scripts for customisation and other tips.
  • https://www.pmwiki.org/wiki/Cookbook/CustomSyntax
  • https://www.pmwiki.org/wiki/Cookbook/Templates
  • https://www.pmwiki.org/wiki/Cookbook/MediaCategories
    Display a page's categories in a box, like Mediawiki does. By default they're only shown inline where they're linked.
• https://www.pmwiki.org/wiki/Skins/Skins

• Namespaces are called groups.
• Interwiki links are called InterMap

Ran into some trouble and found a bunch of preg_replace with /e modifier deprecated in my error_log.

Debugging info here: http://www.pmwiki.org/wiki/PmWiki/Troubleshooting was useful.

1. Uncomment line $EnableDiag = 1; in local/config(.php)
2. Go to [wikiaddress][wikistartpage]?action=ruleset
3. Look for any lines with a file path and line number afterwards. They're easy to spot.
4. Fix, update, or remove whatever's causing the trouble. For me it was just an old skin.
