Same problem. Any results?
We aren’t receiving emails either. Booking successful confirmation message on the front end but user and admin not receiving emails.
I changed it to smtp and tested port 465 and 587 and test emailing with the settings do not work. Just upgraded to the latest stable version.
I experience the slowness as well. yslow had me at a 73 with jquery full calendar plugin. When disabling the full calendar I got a 92. But….I can’t minify js or else it doesn’t load the full calendar at all or any other submit buttons.
Is there another option to load js at end but still have calendar show up??
