Thread:Project:Support desk/RandomInCategory/reply

You have to request index.php from the Script path (mediawiki.org/w/), not from article path (mediawiki.org/wiki/). So the correct link should be:

https://www.mediawiki.org/w/index.php?title=Special:RandomInCategory&wpcategory=Template_extensions

And on enwiki i can't reproduce a redirect to the Special page (that would be false). Please notice, too, that Wikipedias running 1.24wmf20 atm, they will be upgraded tomorrow.
