I came across this issue too and hacked it, see below, and hope it helps!
http://www.eantics.co.uk/category-filter-for-sociable-wordpress-plugin/
Resolved, was going round in circles. The new script for fasthosts does indeed work, I’d changed something else in Admin settings, so didn’t see the impact of it.
Just a bump/update on this.
This is not a host/fasthosts issue. I can include pluggable.php from a separate testmail php file that I’ve created, call wp_mail() passing appropriate function parameters and an email is sent.
So it would appear that either:-
– WordPress is not calling wp_mail or
– It is calling it and passing bad parameters that prevent the function running.
Does this mean anything to anyone – can you help?
Thanks
Ollie
