10 seconds load average per page, if plugin enabled (PRO)

Since i’ve changed my WordPress to HTTPS only, or if there was recently any Smart Donations Update, the load of every page takes 10 seconds!

I’ve tried to debug with re-enable all plugins once-by-once, the bad boy is smart donation pro. i have to deactivate it now.

@developer, could you please run this plugin on https-only pages to detect if it could be reproduced for you?

i’m running the PRO Version.
