[PRO SITES] Pro Sites Stripe

Recently my site switch from PayPal to Stripe payments for Pro sites.

Someone just signed up via Stripe for the first time. It created the site, but didn't auto set it as a 'Pro' site so it had to be upgraded manually.

It also didn't email the user their login for the site, or send them any receipt.
Webhook is added correct.

I've tested with Stripe test mode, and when you signup it just get's stuck loading
Insertion Error: Can't write; duplicate key in table 'wp_aybz499lg3_91_wc_download_log' - The template was not applied. (New Blog Templates - With CREATE TABLE query for Additional Tables)

Also error logs show this:
