moved site, options-general.php not working

Hi

I’ve moved servers and everything seems to be working fairly well, except when I go to add social accounts to Publicise, it 404s on /wp-admin/options-general.php which is appearing in the root rather than the subfolder /wordpress.

I’ve tried changing the functions file in themes, wp-config.php and been through every file I can find on ftp to see if there is anywhere that refers to xyz/wp-admin instead of xyz/wordpress/wp-admin but no luck.

Any ideas where this reference to the root rather than /wordpress subfolder might be, please?

Thanks
