Problema con i permalink o regex?

I meant after the replacement string. I have a / at the end of my RE (right?), but not the end of the replacement.

I don’t know. Perhaps not. In other systems I’ve seen various cruft after the URL (as the example replacement suggests). I’m probably safe removing that last .* to be sure.

####To recap:

Normalization: /forums\/f[0-9]+\/.+-([0-9])+\.html/oldlinks\/topics\/thread-\1

I’ve checked the regex at http://regexr.com/ & it seems to work there. I’ve done something similar in the past. I’m stumped.
