Problem with a Forum plugin

[dimal]

Hello.

It seems that using the plugin with wpForo plugin, the emails are sent but not correctly.

Comparing the two headers (with the plugin enabled and disabled) i see one difference:

Content Type text/plain with the plugin enabled

and

Content Type text/html with the plugin disabled

Any ideas ?

Thanks

Hi @dimalifragis,

Thank you for this report, I successfully reproduced your problem !
This is caused by the fact that wpForo set a wp_mail_content_type filter only during the wp_mail call.
However, with SMTP Mailing Queue, the original wp_mail (which is applying the content type filter) is called just in time (on queue pop).

A solution (patch required) could be to stop overriding wp_mail function, hook on phpmailer_init and store its content in the process queue instead of wp_mail parameters.
However this is a heavy modification and I am wondering if there is a easier way…

Do you have any better solution @hildende ?
