This may work https://ww.wp.xz.cn/plugins/media-deduper/ but I’ve never used it

WordPress asks for your FTP credentials when it can’t access the files directly. This could be a file/folder ownership or permission issue.

As a workaround you can put your FTP credentials directly in wp-config.php

define( ‘FTP_USER’, ‘username’ );
define( ‘FTP_PASS’, ‘password’ );
define( ‘FTP_HOST’, ‘ftp.example.org:21’ );

Chris,

Try temporarily renaming the plugins folder for the site that isn’t working to something like “oldplugins”. If it is a plugin issue, this should resolve things.

If not, I would suggest turning on WP DEBUG in the wp-config.php

by changing the false on this line to true

define('WP_DEBUG', false);

Did you contact your host to see if they had any insight?

Are you sure your email is correct on your admin user?

Did you check your spam?

(You can change the password by accessing the database via a tool like phpMyAdmin too but you should know what you are doing)

Does the same thing happen with all plugins deactivated at the same time? It looks like AutoOptimize is causing an issue so try deactivating that first. If that does not solve it, then deactivate the rest to see if that changes any behavior.

When you deactivated all plugins, did you deactivate them all at the same time?

If yes, are you familiar with turning on WP Debug ?
