Save button does not appear

I managed to export the configuration into a JSON file, then I modified the line: “disallow_spc_cars”:
When I send a form to save, the only special caracters that are not sent to the DB are: <> `
But it does allow to pass the others such as: \ | / { } ( ) [ ] ′ ^ * #
It does not give me a warning message that such characters are not permitted, and instead just deletes the 3 special characters I mentioned first.

Is there some configuration that I’m skipping to make the plugin jump into action?

if I understood your question correctly, the save button does not appear

so if this is the case, put this code in your “functions.php” file of active theme:

add_action('admin_head', function () {
echo '<style>input.button-BENrueeg_RUE_top {position: initial !important;}</style>';
});

I now see the save button, my problem now is that the special characters that I want to restrict are not being blocked.

What I basically need is that special characters are blocked in all of the text inputs I make for the site.

(All of the characters from the “Prevent the use of characters” box I need them blocked from all my text inputs)

by default all characters are restricted in the username when registering, so make sure you don’t use anything else that allows characters, my plugin devloped to not allow.
this option “Prevent the use of characters (Symbols) permitted by wordpress” is to block these characters only:

_ . - @

which are authorized by wordpress, the plugin is compatible with: wp single – BuddyPress (single) – multisite.
