Topic on Extension talk:MassEditRegex

Should i go to the category page (to edit all pages in the old category), and do a text replace?

[[Category: Old Category Name]]

with:

[[Category: New Category Name]]

What about spaces (which get converted to underscore in some cases)?

My rename failed. First i went to the category page https://MyUrl/Category:Delete_Me, which lists one page called Deleteme

Next, i clicked `Edit All`, and got the Mass Edit page with the category pre-loaded.

So far, so good. Then i enter my desired find-replace text:

find: \[\[Category:Delete Me\]\]

replace: [[Category: New Category Name]]

But when i submit, i get an error, saying the page (the page that's in the old category) doesn't exist:
