Bad files found that cannot be deleted

The red flag means “Deleted”.

Files marked with a “deleted” flag are files that are supposed to exist in a normal WordPress installation. Of course, if the file doesn’t exist, you will not be able to find them either using FTP or a file manager. You also cannot use the action “delete” because they already do not exist.

The only thing you can do is to either mark them as fixed or select the option to restore them. If the option doesn’t work, like in your case, is because /wp-content/languages/ either doesn’t exist or PHP cannot write inside.

You’ll have to fix this manually before proceeding with the restoration.

I have no idea how come they don’t exist then. Maybe they were not created when the new site was set up and the language changed.
And why can they not be restored?

/wp-content/languages/ does exist and can be written to.

Gremlins I suppose. Thanks

/wp-content/languages/ does exist and can be written to.

If this statement is true, then I suggest you consult with your hosting provider to investigate possible I/O failures.

When you choose the “Restore” action, after selecting all the files marked as “Deleted”, the plugin opens a connection with WordPress to download a fresh copy of each of these files, then it writes the code into the disk in the corresponding location. The only failures points for this operation are:

1. The destination directory is missing,
2. The destination directory is not writable,
3. The destination is a symlink to a non-accessible resource,
4. The server couldn’t connect to the external WordPress API,
5. Your web browser reset the connection to send the list of files,

Let me know if you would like to have more information.
