hey mate
i just found your post.
i’m on ixwebhosting too … i’ve tried this and i’m not getting results.
i have the 404 page in place, but i don’t know whether i’m directing to the 404 page properly.
if the 404 is in the wordpress root directory, do i need to put anything in front of it? or https://www.mydomain.com/wp-404-handler.php ??
i’m not 100% on how to make the “Relative Path to Custom Error page”
oh, one more question, did you do this before the 2.6 upgrade?? cause that’s when my permalinks broke.
thanks for the help.
