I have just found that any email or contact form function on any website that I have with my 123-reg hosting, does not work.
If I use SMTP function I get the following error
SMTP -> FROM SERVER:550-ATLAS [Home directory didnt exist: 622801,
If I use PHP Mail function I get
Could not instantiate mail function
123 support tell me the following:-
It appears that the folder path specified in your mail form has some flaws. Could you please point to the exact script that you are using, along with its full path, so we can further investigate this for you?
I am a PHP novice and I don't know where to look.
The directory structure of my sites on 123 has a root directory with all my web sites as directories off it. WP then map domains to these subdirectories according to my instructions. Public_html does not appear as a directory anywhere.
I guess I need to know what scripts handle the incorrect directory path that 123-reg say that I have.
What I can't understand is why PHP Mailer does not work either.
I have to say that this is obviously not a wp-mail-smtp problem as no contact form plugin works. Wp-mail just gives me sensible clues.
