Email link shortcode stopped working

WordPress has never provided that short code.

Perhaps you disabled the plugin that did?

That’s strange. I didn’t use a plugin for this and it was definitely working until a recent core update. No plugins have been disabled either.

I understood it was making use of this in wp-includes/formatting.php

These are the only built-in shortcodes: https://developer.www.ads-software.com/plugins/shortcodes/#built-in-shortcodes

I did a search for “WordPress email shortcode” and found https://www.isitwp.com/email-encode-shortcode/ which suggests making your own plugin, adding it to theme functions, or adding it to a code snippets plugin. So, perhaps you recently removed one of those?

I didn’t add any code snippets. All I know is that it was working for quite some time now and then when I visited the site after core update, it wasn’t.

If [email] is not supported, why does this development page include it? Has this functionality been removed since then perhaps?

The above page includes:

To use this in your WordPress Content area all you have to do it wrap it in a short code.

[email][email protected][/email]

I wonder if instead of a core update, it was actually the 3 April update to the Twenty Twenty-Four theme that changed it?

Doesn’t look like it to my eye:
https://themes.trac.www.ads-software.com/changeset?old_path=twentytwentyfour/1.0&new_path=twentytwentyfour/1.1

The section of https://developer.www.ads-software.com/reference/functions/antispambot/ which says, “To use this in your WordPress Content area all you have to do it wrap it in a short code. [email][email protected][/email]” is referring to code example above it.

You will need to first apply the code under “Example” by making your own plugin, adding it to theme functions, or adding it to a code snippets plugin before you can use the email shortcode described below that.

If you had added to Twenty Twenty-Four’s theme functions file without creating a child theme first, then yes updating the theme would have replaced that, since theme updates replace all theme files.

I recommend using a code snippets plugin instead like https://www.ads-software.com/plugins/code-snippets/ to use the example code instead, or just use a plugin specifically made for what you want https://www.ads-software.com/plugins/search/obfuscate+email/ or a more traditional contact form: https://www.ads-software.com/plugins/search/contact+form/

Okay, thanks James for your help and for persevering ????
