I recently installed MediaWiki and FlaggedRevs on my Windows laptop with XAMPP/Apache. I encountered two major issues which strangely are not mentioned on this site. Both are related to accessing rest.php.
Issue one: FlaggedRevs on Apache did not like this url format: localhost/Article
. It prevented rest.php from being accessed. I had to change it to localhost/wiki/Article
.
Issue two: FlaggedRevs on Apache did not work on subpages because their titles contain forward slashes. To fix this you need to set AllowEncodedSlashes to "NoDecode". On Apache, this feature is set to "Off" by default.
I wrote about these problems at bigger length on the support desk, see here. I do believe this site should have notes about these hurdles to prevent other people from wasting time on them like I did.
