I’m trying to improve the permalink redirects on the vbulletin importer. Vbulletin can have any of several URL formats. My solution is to create generic permalinks which will then be handled by permalink normalizations. Like this: Old URL: http://somesite/forums/f38/slug-blah-blah-blue-11769.html …

I thought that perhaps my problem was that I didn’t need to \ escape the /s in my replacement string, but that doesn’t seem to have solved it either. And I’ve confirmed that the regex works, it’s the replacement that’s broken. If I create a permalink badword-11769 and use this /forums\/f[0-9]+\/.…
