I have a wordpress install running woocommerce subscriptions and memberships that's been working fine for weeks, and now all of a sudden I'm receiving the following error message:
'fatal error: Uncaught exception 'Exception' with message 'SSL certificate problem: unable to get local issuer certificate' in... .../wp-content/plugins/woocommerce-subscriptions/includes/gateways/paypal/includes/abstracts/abstract-wcs-sv-api-base.php on line 154'
This message is in the admin area at the following location: wordpress admin > woocommerce > settings > checkout
It's also present on the front-end when trying to view a single product page.
i've tried disabling all plugins to determine any possible conflicts and the route of the issue, only to determine that the issue persists only when the Woocommerce Subscriptions plugin is active.
