Links to Twitter profiles in the old #! format, fixed to x.com in a single pass.
What it does
It searches your blog's content for Twitter links in the old #!/username format (or its encoded variant #%21/username), including those on mobile.twitter.com and m.twitter.com, and proposes rewriting them to https://x.com/username. It checks posts, pages and drafts.
You decide what changes: you review the proposed changes and apply the ones you want. Before writing to each post it checks that nobody has edited it since the analysis; if it has changed, it skips it and asks you to analyse again.
Why a redirect is not enough
Everything after the # in an address stays in the browser and never reaches the server. That is why these links cannot be fixed with a redirect: they have to be changed in the content itself, and doing it by hand on a blog with years of posts takes a long time and it is easy to miss some.

- Activate the plugin and go to Tools → Fix Twitter Links: you see every affected post with its Cambios propuestos (Proposed changes), from the old address to the new one.
- Untick the posts you do not want to touch (they all start ticked) and press Aplicar cambios seleccionados (Apply selected changes).
- The page confirms when there are no links left matching the pattern.
Requirements
- WordPress 5.2 or later and PHP 7.4 or later.
