With latests versions (including 5.10.17) I can't send from frontend in manual. It says emails will be sent as soons as possible. BUT IS IN MANUAL and I don't want to setup a cronjob.
The emails get in te queue and after two seconds the popup window that used to execute the AJAX manual sending with a time counter is not showing anymore, instead the newsletter list view loads in the browser with a Cancel Button available.
When I do the same from BACKEND it works as expected as it ever did, a popup listing the batch email sending and a countdown until next batch of mails.
I checked all configuration but did't discover any new adjustment to do.
I use AdminTools but never had to do nothing
